Answer:
4 or -4 !
Step-by-step explanation:
edit... isolate the variable, so divide 5 on both sides. then take the absolute value of d which is d. therefore d = 4 or -4! it's both positive and negative because absolute value you set it equal to a positive and negative!
Answer:
d. 40
Step-by-step explanation:
2x + x +( x + 20) have to all equal 180 degrees in a triangle.
2x + x + x + 20 = 180
2x + 2x + 20 = 180
4x + 20 = 180
4x = 180 - 20
x = (180-20) / 4
x = 160 / 4
x = 40
Answer:
T-shirts and
Baseball Caps
Step-by-step explanation:
GIVEN: The ninth graders at a high school are raising money by selling T-shirts and baseball caps. The number of T-shirts sold was three times the number of caps. The profit they received for each T-shirt sold was
, and the profit on each cap was
.
TO FIND: If the students made a total profit of
, how many T-shirts and how many caps were sold.
SOLUTION:
Let the total number of T-shirts sold are 
Let the total number of Baseball Caps sold are 
Profit received on each T-shirt 
Profit received on each Baseball Caps 
Total profit received on T-shirts 
Total profit received on Baseball Caps 

Also,
The number of T-shirts sold was three times the number of caps.

putting in equation,





Hence total
t-shirts and
baseball Caps were sold.
87.5
Tall. /. Shadow
3 / 1.74=. X /. 50.75
Cross multiply
152.25= 3x
Divide by 3
X= 87.5
Answer:
<u><em>y = -(2/5)x+4</em></u>
Step-by-step explanation:
The 2 points are 0,4 and 5,2. If you want to find the equation, you need slope. slope = rise/run = -2/5.
y = mx + b. The b is the y intercept, so it's 4.
The equation is <u><em>y = -(2/5)x+4</em></u>
