Answer:
70
Step-by-step explanation:
right angle is 90 degree..
so u subtract 90 with 20
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.

57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187

x = -10
Answer:
Let x represents the number.
Given the statement: "Three less than the product of a number and two, increased by five".
"Product" means multiply
"Product of a number and two" translated to
"Three less than the product of a number and two" translated to 2x - 3
Increased by 5 means +5
then;
the given statement becomes;
Therefore, the expression that represents "three less than the product of a number and two, increased by five" is
1.4-0.04x=5.20
-0.04x=-1.4+5.20
-0.04x=3.8
X=3.8/-0.04
X= -95 To check use substitute both sides should equal 1.4-0.04(-95)=5.20
1.4+3.8=5.20
5.2=5.2
