Answer:
135
Step-by-step explanation:
(7+3)^2 + (8-1) * 5
Parentheses first
(10)^2 + (7) * 5
Exponents next
100 + 7*5
Multiply
100 + 35
Add
135
Side a = 10.98991
Side b = 11.69522
Side c = 4
Angle ∠A = 70° = 1.22173 rad = 7/18π
Angle ∠B = 90° = 1.5708 rad = π/2
Angle ∠C = 20° = 0.34907 rad = π/9
Answer:
w = 8
Step-by-step explanation:
7w = 56
Divide both sides by 7
w = 56/7
w = 8
The solution is (5,2)
Step-by-step explanation:
From the third column the equation for sum of equivalent system is given as;
8x = 40
divide both sides by 8 to get value of x
8x/8 = 40/8
x=5
Using the value of x in the fifth column's first equation will be;
4x +4y =28
4(5) + 4y =28
20 +4y =28
4y= 28-20
4y=8
divide both sides by 4 to get y
4y/4 =8/4
y=2
The solution is x=5 and y=2 written as (5,2)
