5x + 2y = 7
Solve for y
The correct answer is attached below:
Answer:
y= 7/2-5x/2
Step-by-step explanation:
When two angles are supplementary their sum is equal to 180 degrees. Let x equal one of two supplementary angles. If the other angle is equal to 67 degrees, write
an equation in terms of x for the sum of the two angles.
since we know supplementary angles equal 180 degrees, we know that 67 plus x must equal 180 degrees, so the equation for this problem would be
67+x=180, and x is equal to 113

A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes. How often do they blink at the same time?A.Every 14 minutesb.Every 24 minutesc.Every 48 minutesd.Every 2 minutes
Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.

A ball is dropped from a height of 8 feet. If every time it bounces, it bounces 60% of its previous height, what is the total distance traveled by the ball?
Answer:
20feetStep-by-step explanation:
Initial height of the ball = 8feet
If it bounces 60% of its previous height, its new height will be;
60% of 8
= 60/100 * 8
= 480/100
= 4.8 ft
If it bounces 60% of its current distance, new height will be expressed as;
60% of 4.8
= 0.6 * 4.8
= 2.88
The height of the ball will keep reducing and form a geometric progression of the form 8, 4.8, 2.88...
In order to get the total distance traveled by the ball, we need to calculate the sum to infinity of the sequence;
S∞ = a/1-r where;
a is the first term = 8
r is the common ratio
[tex]r = \frac{4.8}{8} = \frac{2.88}{4.8}\\r = 0.6[/tex]
Substitute into the formula;
S∞ = a/1-r
S∞ = 8/1-0.6
S∞ = 8/0.4
S∞ = 20feet
Hence the total distance traveled by the ball is 20feet

Jack bought 500 shares in Glastonbury Goods at $17.85 per share on January 18, 2015. On January 25, 2017, he sold 300 shares after its price had dropped to $15.25 per share. He bought 250 more shares on January 31, 2017 when the price had fallen to $11.90 a share. He sold all of his stock at $18.00 per share on February 5, 2017. How much of a profit/loss did Jack make over the course of his investment? ____________________ profit or loss
Answer:
$775 profit
Step-by-step explanation:
Here, we want to know how much profit or loss Jack made;
he sold 300 shares at $15.25
Amount lost on this will be;
(17.85-15.25) * 300 = -$780
The number of shares he sold at $18 will be the 250 he bought now, and the 200 left unsold before
So profit now will be;
200(18-17.85) + 250(18-11.9)
= $30 + $1525 = $1555
So he made $1555 and lost $780
The amount of profit made is $1555-$780 = $775
Find the slope of the line that goes through the points (9,-13) and (7,3).
hi
You have two points A ( X;Y) and B ( X ; Y)
slope is : ( Yb -Ya) / (Xb -Xa )
(3 - (-13) ) / ( 7 - 9) = (3 +13) / -2 = 16/-2 = - 16/2 = -8
slope is -8
Answer:
-8
Step-by-step explanation:
The slope formula is as follows:
m = y2 - y1 / x2 - x2
You would first plug in the points into the formula, and this is what you would get:
m = 3 - (-13) / 7 - 9
From there, because of additive inverse, the negative signs would become + signs.
m = 3 + 13 / 7 - 9
You would now add/subtract.
m = 16 / -2
And lastly, you would simplify.
m = 8/-1
8/-1 is the same thing as a slope of -8.

Answer:
m∠W is 28°
m∠X is 24°
Step-by-step explanation:
In any triangle, the measure of an exterior angle at one vertex of a triangle equals the sum of the measures of the two interior angles opposite to this vertex
In the given figure
∵ ∠WYZ is an exterior angle of Δ XYW at vertex Y
∵ ∠W and ∠X are the interior angles of Δ XYW opposite to the vertex Y
→ Use the fact above
∴ m∠WYZ = m∠X + m∠W
∵ m∠WYZ = 52°
∵ m∠X = 3y°
∵ m∠W = (4y - 4)°
→ Substitute them in the equation above
∵ 52 = 3y + 4y - 4
→ Add the like terms
∴ 52 = 7y - 4
→ Add 4 to both sides
∵ 52 + 4 = 7y - 4 + 4
∴ 56 = 7y
→ Divide both sides by 7
∵ [tex]\frac{56}{7}[/tex] = [tex]\frac{7y}{y}[/tex]
∴ 8 = y
→ Substitute y in the measures of ∠X and ∠W
∵ m∠X = 3(8)
∴ m∠X = 24°
∵ m∠W = 4(8) - 4 = 32 - 4
∴ m∠W = 28°
Evaluate: f(2) if f(x) = 4 - 2x
f(2) = 0
f(2)= 2
f(2)= 4
f(2) = 8
Answer:
f(2) = 0
Step-by-step explanation:
Evaluate: f(2) if f(x) = 4 - 2x; plug in 2 for x
f(2) = 4 - 2(2) = 4 - 4 = 0
Answer:
f(2) = 0
Step-by-step explanation:
Put 2 in the place of x,
f(2) = 4 - 2(2)
f(2) = 4 - 4
f(2) = 0

Brian bought a jacket that cost d dollars. He paid the clerk $60,00 He received $7.39
in change. How much did Brian pay for the jacket?
Answer:
52.61 is what Brian payed for the Jacket.
Step-by-step explanation:
52.61 + 7.39 = 60$ in total.
Answer:
ok so a jacket would never cost 60,00 i think you meant 60.00 so it would be $52.61 for the jacket
Step-by-step explanation:
Subtract 7.39 from 60
if you really did mean 60000 the answer would be 5992.61

Using the Triangle Sum Theorem, find x and the missing angles (2x +1) (5x +5) x= Angle (2x+1) = Angle (5x+5) =
Answer:
x = 12
(2x + 1)° = 25°
(5x + 5)° = 65°
Step-by-step explanation:
By the property of a triangle,
Sum of all angles of a triangle is 180°
In the given right triangle,
(2x + 1)° + 90° + (5x + 5)°= 180°
7x + 96 = 180
7x = 180 - 96
x = [tex]\frac{84}{7}[/tex]
x = 12
Angle (2x + 1)° = 2(12) + 1 = 25°
Angle (5x + 5)° = 5(12) + 5 = 65°
Therefore, all three angles of the right triangle are 25°, 90° and 65°.

Step-by-step explanation:
The smaller triangle and the bigger triangle have the same angle of 60 on one side.
They also have a common point at the top, which is also called a common angle.
You only need two angles to show that two triangles are similar, because the other angle has to be the same because all angles in a triangle add up to 180.

A small-town newspaper examines its daily circulation. Last week, it sold 200 newspapers daily. This week, it sold 186 newspapers daily. Part A: What is the percent decrease in the newspaper's circulation since last week? Part B: If circulation decreases by the same percent next week, what will the daily circulation be?
Answer:
7%
173
Step-by-step explanation:
Given that :
Daily sales last week = 200
Daily sales this week = 186
% decrease in newspaper circulation :
(Decrease / initial amount) * 100%
((200 - 186) / 200) * 100%
(14 / 200) * 100%
0.07 * 100%
= 7%
Part B: If circulation decreases by the same percent next week, what will the daily circulation be?
7% decrease the following week :
(100% - 7%) of 186
93% * 186
0.93 * 186
= 172.98
= 173
