In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
PQRS
PS = -1 + 4x
QR = 3x + 3
QR = ?
Step 02:
PS = QR
-1 + 4x = 3x + 3
4x - 3x = 3 + 1
x = 4
QR = 3(4) + 3
= 12 + 3
= 15
The answer is:
QR = 15
64.18 - 61.06 = 3.12
Emily was 3.12 seconds faster than Daniel.
Answer:
Tyler has 40 video games
Step-by-step explanation:
x= chas
y= tyler
z= total
x+y=z
25+y=65
-25 -25
y= 40
Answer:
Simplified :
x = 13/12
(Mixed number) :
x = 1 1/12
Step-by-step explanation:
The y answers would be 11, 8, 5, 2, -1.
To find these parts of the table, we simply put the x value in for x and solve for y. The first two are done for you below.
WHEN x = -2
y = -3x + 5
y = -3(-2) + 5
y = 6 + 5
y = 11
WHEN x = -1
y = -3x + 5
y = -3(-1) + 5
y = 3 + 5
y = 8
