Answer:
The answer is $8.00.
Step-by-step explanation:
First, you have to find how much for each app so you have to divide by 3 :
3 apps = $2.40
1 app = $2.40 ÷ 3
1 app = $0.80
Next, you have to multiply it by 10 :
1 app = $0.80
10 apps = $0.80 × 10
10 apps = $8.00
Answer:
The cost will be the same after 1 month
Step-by-step explanation:
Step 1: set up the equation
club A= 28x+24 club B= 35x+17
club A=club B: 28x+24=35x+17
Step 2: Get rid of the smallest X
28x+24=35x+17
-28 -28
24=7x+17
Step 3: Get rid of the constant next to the variable to isolate the variable
24=7x+17
-17 -17
7=7x
Step 4: Inverse operation to remove variable
7÷7x=7x÷7x
1=1
I hope this helped, im not too good at explaining but im positive the solution is correct.
Answer:
4
Step-by-step explanation:
3x² + 2x - 4
3(-2)² + 2(-2) - 4
3(4) - 4 - 4
12 - 4 - 4
12 - 8
= 4
Answer:
b
Step-by-step explanation:
When you match the pattern of (x+y)⁴ to (a+b)ⁿ, you see that a=x, n=4. Then the first term aⁿ can be found by substituting these values for "a" and "n":
... x⁴
