How many solutions does the equation have? 4h + 2 = 3h - 7
Answer:
1 solution
Step-by-step explanation:
4h + 2 = 3h - 7
Subtract 3h from both sides:
(4h + 2) - 3h = (3h - 7) - 3h
h + 2 = -7
Then, subtract 2 from both sides to isolate h:
(h + 2) - 2 = (-7) - 2
h = -9
There is one solution, -9.

You must show how you get your answer.
Yes, Chris has enough money to buy 30 pens and 30 folders.
What is money?Money is a commodity that is widely accepted as a medium of economic exchange. It is the primary means of expressing prices and values; as currency, it circulates anonymously from person to person and country to country, facilitating trade; and it is the primary measure of wealth.Given:
3 pens cost £2.25.5 folders cost £5.80.Chris wants to buy 30 pens and 30 folders.He only has £60.So, the cost of 30 pens will be:
When: 3 pens = £2.25Then: 3×10 = £2.25×1030 pens = £22.5Similarly, the cost of 30 folders will be:
When: 5 folders cost £5.80Then: 5×6 = £5.80×630 folders = £34.8Cost of 30 pens and 30 folders = £22.5 + £34.8 = £57.3
Given that Chris has £60.Therefore, yes Chris has enough money to buy 30 pens and 30 folders.

a = h/b, solve the formula for b
a = h/b
x b, both sides
ab = h
÷a
b = h/a
B = h/a
Hope this helps!
Answer: b = h/a
Step-by-step explanation: What you need to do is to get b by itself and to do that you have to move b to the other side because it's being divided by b. To do that you multiply by b on both sides.
1) ab = h
Now, isolate b by dividing a into both sides.
2) b = h/a
Now, you have b alone you know what b is equal to.

A safety regulation states that the height h of a guardrail should be 106 centimeters with an absolute deviation of no more than 7 centimeters. Write and solve an absolute value inequality that represents the acceptable heights of a guardrail.
The absolute value inequality is
.
The acceptable range of heights of a guardrail are
cm to
cm.
A guardrail's acceptable height range is 99cm to 113cm and the definite absolute value inequality is as follows | h - 106cm | ≤ 7cm,
How to define an inequality? A statement stating that one quantity is less than or (greater than) another.An inequality solution is a number that, when replaced for the variable, makes the inequality true.We understand that the height must be 106cm with a maximum absolute deviation of 7cm.
As a result, the maximum height is:
106cm plus 7cm = 113cm
The bare minimum is:
99cm = 106cm -7cm
This is represented by the absolute value equation:
| h - 106cm | ≤ 7cm
In which h is the guardrail's height.
A guardrail's acceptable height range is 99cm to 113cm.

Answer:
{x|10.132 < x < 10.133}
Step-by-step explanation:
I think this will be the answer
The required value of the variable x can be found as 10.1325.
What is linear inequality?Linear inequality refers to the relation between a linear algebraic expression to some known value that contains inequality sign.
Unlike a linear equation it can have a range of values inside an interval.
The given inequality is 10.132 < x < 10.133.
It implies that the value of x lies between 10.132 and 10.133.
Write the given numbers up to four decimal places as,
10.1320 and 10.1330
Then, the required value of x can be written as 10.1325.
Hence, the value of x can be found by writing the numbers in equivalent form as 10.1325.

Answer:
2x + 2 + h.
Step-by-step explanation:
F(x+h) is f(x) where x+h replaces x:-
f(x + h) = (x + h)^2 + 2(x + h) - 3
[f(x+h) - f(x)] / h
= (x + h)^2 + 2(x + h) - 3 - (x^2 + 2x - 3) / h
= [x^2 + 2hx + h^2 + 2x + 2h - 3 - x^2 - 2x + 3] / h
= (2hx + h^2 + 2h) / h
= 2x + 2 + h
The limit of [f(x+h) - f(x)] / h as h ----> 0 is 2x + 2.
We refer to 2x + 2 as the derivative of x^2 + 2x - 3.

A right triangle is a triangle, of which one of the three angles is a right angle. In accordance with Euclidean geometry, the sum of the measures of the internal angle is equal to 180°. Then,
m ∠ A + m ∠ B + m ∠ C = 180°
90° + 34° + m ∠ B = 180°
124° + m ∠ B = 180°
m ∠ B = 180° - 124°

calculate how many acres are in the southwestern 1/4 of the northern 1/2 of the eastern 1/2 of section 14.
Section 14 makes about 40 Acres.
640 acres make up a square mile.
Given are the southwest quarter, the northern half, and the eastern half.
Consider that 2x2x4=16.
640 divided by 16 equals 40 acres.
40 acres make up Section 14.
How do you estimate the value per acre?
At first appearance, the calculation for calculating price per acre (PPA) appears to be rather straightforward.It is calculated by dividing the value of your property (v) by the number of acres (a). Therefore, v / a = PPA. As an acre is already regarded as a squared number, you don't need to worry about squaring the measurement.

[tex] {x}^{2} + 4x - 7 = 0 \\ → {x}^{2} + 4x = 7[/tex]
Add the square of the half of the coefficient of the unknown(x) to both sides of the equation.
[tex] {x}^{2} + 4x + ( \frac{4}{2} {)}^{2} = 7 + ( \frac{4}{2} {)}^{2}[/tex]
[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + (2 {)}^{2} [/tex]
[tex] {x}^{2} + 4x + (2 {)}^{2} = 7 + 4[/tex]
Bring out x and 2 and square them as shown below:

Gordon invests $2,500 for 20 months at a simple interest rate of 12.4%. the amount of interest received is found by i=prt since r= 0.124. i=0.124 x p x t. what are p and t?
The p and t represent Principal and time and interest is 517.7
We are given the formula to find the interest. So, the formula is -
I = (PRT) ÷ 100
In this formula, I refers to interest, P refers to Principal, R refers to rate of interest and T refers to time. Time will be in years and division by 100 is done for rate of interest.
Keep the values in formula to calculate the interest -
As per the known fact, 12 months = 1 year
So, 20 months = (1 ÷ 12) × 20
20 months = 1.67 years
Interest = (2500 × 12.4 × 1.67) ÷ 100
Performing multiplication in numerator
Interest = 51,770 ÷ 100
Performing division to find the interest
Interest = 517.7
Hence, p refers to principal and t refers to time. The interest that Gordon will receive will be 517.7.

The not common definition of the Geometric distribution is the variety of trials till the primary achievement.. The following is an instance for the distinction among the Binomial and Geometric distributions: If a own circle of relatives comes to a decision to have five youngsters, then the variety of girls (successes) within side the own circle of relatives has a binomial distribution. If the own circle of relatives comes to a decision to have youngsters till they have got the primary lady after which stop, the the variety of youngsters within side the own circle of relatives has a Geometric distribution . A variant at the Geometric distribution is counting the variety of failures till the primary achievement, after which the variety may be 0,1,2,... In the instance it might be counting the variety of boys within side the own circle of relatives earlier than the primary lady turned into born, and now no longer the entire variety of youngsters. The distinction among the 2 versions is usually 1.
