Answer:
67.5?
Step-by-step explanation:
the top two looked like the same degree so solve 2x+10=145 ig
Answer:
m<x = 48
m<y = 132
Step-by-step explanation:
Since x and y are supplementary angles, that means their sum is 180 degrees.
And we are given that y is 12 less than 3 times the measure of x. With this information we can make a system of linear equations.
x + y = 180
y = 3x - 12
So now plug in the value of y into the first equation.
x + y = 180
x + (3x - 12) = 180
x + 3x = 192
4x = 192
x = 48
And then plug this computed value of x back into the first equation to find the measure of y.
x + y = 180
48 + y = 180
y = 180 - 48
y = 132
So the measures of the angles are as follows:
m<x = 48
m<y = 132
Cheers.
Answer:
Step-by-step explanation:
Step-by-step explanation:
Wai 1unit+45
Cheryl 1unit
Zheng 4units+180
Altogether 6units+225=510
6units = 510-225
6units=285
1unit=285÷6
= $47.5
So Wai =47.5+45 = 92.5
Cheryl =47.5
Zheng =4×47.5+180 =370
370-47.5=$322.5
Answer $322.5
Answer: -418, 728, 446, -429, 1159, -696
Step-by-step explanation:
1. 
.
2. 
.
3. 
.
4. The sum of 429 and 429 is 
. We need to subtract this from 429, so 
.
5. The sum of 510 and 319 is 
. Subtracting -330, we get 
.
6. Call the unknown number "
". Then 
, so 
. (Think about it.)
