Answer:
The number is 385.
Step-by-step explanation:
The 5 is in the ones place so you put that at the end. The digit in the tens place is 3 plus the digit in the ones place which is 5 so 3 + 5 = 8 so the 8 is in the tens place. The digit in the hundreds place is 2 less than the digit in the ones place which is 5 so 5 - 2 = 3 so the 3 is in the hundreds place
Answer:
b. a=-12
Step-by-step explanation:
3a-5a+10=34
multiply -5 times a and -2
-2a+10=34
-5a from 3a
-2a=24
subtract 10 from both sides
a=-12
-2a divided by both sides
Answer:
x = 20
y = 73
Step-by-step explanation:
8x - 87 + 7x - 33 = 180
15x = 180 + 87 + 33
15x = 300
x = 20
8x - 87 = y
160 - 87 = y
y = 73
Let Q= the number of quarters and D= the number of dimes.
Q+D= 40 coins
0.25Q+0.1D= $7.75
Rewrite equation 1 as: D = 40-Q and substitute into equation 2
0.25Q+0.1(40-Q)= 7.75 Simplify the left side
0.25Q+4-0.1Q= 7.75 Subtract 4 from both sides
0.25Q-0.1Q= 3.75 Convime like terms on left side
0.15Q= 7.75 Divide both sides by 0.15
Q=25 and D= 40-Q
D= 40-25 which is 15
So Jenna had 25 quarters and 15 dimes.
<span>To check multiply 25 x 25 and 15x10 which equals 625 and 150 this equals 775 so this is 7.75</span>
