Answer:
The measure of the angles are 40 degrees and 50 degrees
Step-by-step explanation:
Let
x ----> the measure of one angle in degrees
y ----> the measure of the complementary angle in degrees
we know that
If two angles are complementary, then their sum is equal to 90 degrees
so
----> equation A
we have that
----> equation B
Substitute equation B in equation A and solve for y
Find the value of x
therefore
The measure of the angles are 40 degrees and 50 degrees
Cows=10 units
horses=3 units
if 20 cows then
10 units=20 then
1 unit=2
so horses=3 units
1 unit=2
2 times 3=6
6 horses

Answer:
5.Let Alisha= A
Riley= R
Jordan= J
A=7
R=A+4= 7+4= 11
J=3*7= 21
Riley=11
Jordan=21
6.Red Marbles= 18
Yellow Marbles=18*3=54
Green Marbles=18-10= 8
7.This year= 28 eagles
Last year=28/4 =7 eagles
Difference= 28-7 = 21 Eagles
8.Joel= 8 pictures
Taylor= 8*3= 24 pictures
1 Row= 4 pictures
24 pictures= 24/4= 4 rows
Answer:$6/Yard
Step-by-step explanation:
You make it into an algebraic expression, 2.5x=15.
Then, you divide both sides by 2.5
2.5x=15, 2.5x/2.5 =x, 15/2.5=6.
x=6.
x represents the amount of dollars per yard.
