Step-by-step explanation:
let x be the another angle
so
x+40=90
x=90-40
x=50
The measure of missing angle is 50

Let, the cost of a belt = x
cost of a wallet = y
Then, system of equations would be:
x + y = 42
7x + 4y = 213
Multiply 1st equation by 4,
4x + 4y = 168
Substitute it from 2nd equation,
3x = 45
x = 15
Now, substitute it in 1st equation,
15 + y = 42
y = 42 - 15 = 27
In short, Belt costs $15 and wallet costs $27
A)
15x4=60
27x4=108
60+108=
four belts and four wallets cost 168
B) 3x15=
<span>three belts cost 45</span>
Answer:
168
Step-by-step explanation:
LxWxH
L=6
W=4
H=7
6x4=24
24x7=168
Answer:8.6 x 104
Step-by-step explanation:
Subtract 15 from both sides
You want to focus on isolating the variable (x)
