Answer:
Subtraction property ; x = 3.25
Division property ; - 6
multiplication property ; - 125
Addition property ; 13
Step-by-step explanation:
A.)
x + 3.75 = 7
Using the subtraction property : subtract 3.75 from both sides
x + 3.75 - 3.75 = 7 - 3.75
x = 3.25
B. )
–3b = 18
According to the division property :
Divide both sides by - 3
-3b / - 3 = 18 / - 3
b = - 6
C.)
m/5 = - 25
Using the multiplication property :
m/5 * 5 = - 25 * 5
m = - 125
D.)
m – 4 = 9
Using the addition property :
Add 4 to both sides :
m - 4 + 4 = 9 + 4
m = 13
Answer:
After 4 weeks they have $413
After 5 weeks they have $485 (more than enough money)
Step-by-step explanation:
we know that here are 3 people saving up this money and we know that they have already saved 125 dollars.
if each saves $24 per week... 24*3=72 (total profit per week)
for 4 weeks... 72*4=288
288+125(already saved up)= 413
If they go one more week and save up another 72 dollars in 1 week this will bring them past their goal
15 girls 12 boys 5x3=15 and 4x3=12 so 15 girls 12 boys
Answer:
2
Step-by-step explanation:
x f(x)
−3 −1.5
−2 −1
−1 −0.5
0 0
1 0.5
2 1
3 1.5
This table shows the input and output values for a linear function f(x).
Now, two inputs which are four values apart are say -3 and 1 and the corresponding outputs are - 1.5 and 0.5.
Therefore, the positive difference of outputs is [0.5 - (- 1.5)] = 2 (Answer)
