Answer:
just add all the number and divide them .
Y = x + 1....so we sub in x + 1 for y in the other equation
2x + y = 7
2x + x + 1 = 7 ....combine like terms
3x + 1 = 7....subtract 1 from both sides
3x = 7 - 1
3x = 6 ....divide both sides by 3
x = 6/3
x = 2
y = x + 1
y = 2 + 1
y = 3
so ur solution is : (2,3)
Volume/V=length x width x height
So, V=4.5 x 2 x 2
V =18
You would divide a side of the larger rectangle by the smaller rectangle and it would give an answer of 1.5. To check if your correct times your answer by one of the sides on the smaller triangle
Answer:
QS = 34
Step-by-step explanation:
if R is the midpoint, then the two divided segments are equal to each other.
5x - 3 = 21 - x
Add x
6x - 3 = 21
Add 3.
6x = 24
Divide 6.
x = 4
Substitute this x value into any equation.
5(4) - 3 = 20 - 3 = 17
So half of QS is 17.
QS = 17 * 2 = 34
