HELPPPPP its geo and I need help
Answer:
61
Step-by-step explanation:
first we set <B and <E equal to each other to find x (they are equal because it is a given in the phrase below the pics)
5x + 8 = 7x - 12
5x + 20 = 7x
20 = 2x
10 = x
now we know x is 10, so substitute it into an equation to find the measure of the vertex of the triangles
5(10) + 8 = 58
subtract 58 from 180 to find what the base angles are combined
180 - 58 = 122
since there are two congruent base angles (the base angles of isosceles triangles are always congruent), we have to divide 122 by 2 to find the measure of a base angle
122 ÷ 2 = 61
<F is a base angle, so <F is 61
To add or subtract fractions, what must you have?
Answer:
You need a common denominator.
Step-by-step explanation:
3/4+2/3
9/12+8/12
Answer:
Equal denominators/common denominators
Step-by-step explanation:
You need to have equal denominators. If you do not, then you have to multiply the denominators against each other as well as multiplying the same number to the numerator. If a number is a factor of one of the numbers then multiply the number by its other factor so as to get the same number.
Ex. 1
First one explained:
2/3 + 4/5
1/3 * 5/5 = 5/15
2/5 * 3/3 = 6/15
5/15 + 6/15 = 11/15
Common denominator = 15
Ex. 2
Second one explained:
2/8 + 1/4
2/8 + 1/4*2/2 = 2/8 + 2/8
= 4/8
Common Denominator = 8Hope this helped,

Write the word sentence as an equation. Then solve.
10 more than a number c is 3.
Equation:
Solution: c=
Answer:
I would say c is .3 . The equation is 3÷10
Step-by-step explanation:
because its saying c times 10 is 3 and the reverse of multiplication is division. So you divide 3 by 10 to find c Hope This helps!! C is 0.3

Find the equation of the line. Use the exact numbers.
Equation: y = _____ x _____
if f(x)=10x+3 whar is the value when f(x)=19
Answer:
x = 1.6
Step-by-step explanation:
Given f(x) = 10x + 3 and f(x) = 19, then equate right sides, that is
10x + 3 = 19 ( subtract 3 from both sides )
10x = 16 ( divide both sides by 10 )
x = 1.6
Answer:
x = 1.6Step-by-step explanation:
Given
f(x)=10x+3and
f(x) = 19 ⇒ x = ?Solution
10x + 3 = 1910x = 16x = 16/10x = 1.6With a coupon, you get a pair of shoes that normally cost $80.00 for 30% off. How much is the discount?

A town population of 14000 and grows 3.5% every year. What will be the population after 14 years to the nearest whole number
Answer:
22662
Step-by-step explanation:
Since the growth is exponential, your equation will be y = a • b^x. a being the beginning amount, b the percentage it increases by, and x is the time taken.
y = 14000 • 1.035^14
= 22661.72
Round your answer since people can only be integers and your answer is a population of 22662
Why can you use cross products to solve the proportion StartFraction 18 over 5 EndFraction = StartFraction x over 100 EndFraction for x?
9514 1404 393
Answer:
it is application of the multiplication property of equality
Step-by-step explanation:
You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.
For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.
[tex]\dfrac{18}{5}=\dfrac{x}{100}\qquad\text{given}\\\\\dfrac{18\cdot5\cdot100}{5}=\dfrac{x\cdot5\cdot100}{100}\qquad\text{multiply by $5\cdot100$}\\\\18\cdot100=5\cdot x\qquad\text{cancel common factors; looks like cross product}[/tex]
__
Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.
[tex]\dfrac{18\cdot100}{5}=x\qquad\text{divide by 5}[/tex]
Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.

can someone please help .. will mark brainliest !
Answer:
B and B
Step-by-step explanation:
The first one is B because all of the slopes are negative except B. And so I think that's the correct answer
The second one I know is B for sure, I remember learning it in 8th grade 2 years ago.
It's really just the first one I am second guessing myself on but B and B make sense to me :)
