8b+12-b=8+7b+4
7b+12=12+7b
-7b
7b-7b+12=12
-12 -12
0= 12-12
0=0
Answer:
The value of x is 8.
Step-by-step explanation:
In triangle PQR and XZY,



By AA property of similarity, we can say that

The similarity statement is
.
The corresponding sides of similar triangles are proportional. Since both triangles are similar, so







Therefore the value of x is 8.
Answer:
x = -9
Step-by-step explanation:
The attachment shows the labeling according to the problem statement.
The overall length is the sum of the constituent segment lengths, so ...
FG + GH = FH
(10 +x) +(7) = (2x +26)
x +17 = 2x +26
x -9 = 2x
-9 = x
__
<em>Check</em>
Then the segment length FG is ...
10 +x = 10 -9 = 1
and the overall length is ...
2x +26 = 2(-9) +26 = -18 +26 = 8
That is, 1 + 7 = 8.
Answer:
The decimal number is 0.964
Step-by-step explanation:
we have

step 1
Multiply each fraction by the whole number

step 2
Convert each fraction in a decimal number
Remember
Move the decimal point to the left as many places as there are zeros in the factor.
Move the decimal point one step to the left (10 has one zero).
Move the decimal point two steps to the left (100 has two zeros)
Move the decimal point three steps to the left (1000 has three zeros)

step 3
Adds the number

Let M = #miles driven
Plan 1: .50M + 70 = total cost
Plan 2 .70M = total cost
To know how far she would drive to have an equal cost for either plan just set the equations equal to each other
.70M = .50M + 70
subtract .50M from both sides
.20M = 70
M = 70/.20 = 350 miles
Check the answser:
Plan 1: .50(350) + 70 = 175 + 70 = $245
Plan 2: .7(350) = $245
they are equal so our answer checks as correct
