Step-by-step explanation:
m+3=9
m=9-3=6
The second question I guess that it is solved like
2x+5=11
2x=11-5
2x=6
X=3
Or the other qusetion 5x-8=27
5x=19
X=19/5
I don't know the machine so sorry
Answer:
d) 63 square units
Step-by-step explanation:
x = 3 units (base - b)
y = 6 units (width - w)
h = 7 units (length and height - l and h)
- Area of a rectangle: l*w
- Area of a triangle: 1/2*b*h
For the triangles:
Area of a triangle: 1/2*b*h
A = 1/2 * 3 * 7
A = 1/2 * 21
A = 10.5
*Since there are two triangles, it would be 10.5 * 2 = 21
For the rectangle:
Area of a rectangle: l*w
A = 7 * 6
A = 42
Now, we add them together:
A = 42 + 21
A = 63 square units
Therefore, the area of the parallelogram is 63 square units
Hope this helps!

Answer:
10
Step-by-step explanation:
360=95+95+15+7x+15+7x
360-95-95-15-15=7x+7x
140=14x
140/14=x
10=x

Kindly check explanation
Step-by-step explanation:
The hypothesis :
H0 : μ = 3000
H0 : μ ≠ 3000
The test statistic :
(xbar - μ) ÷ (s/√(n))
xbar = 3500
μ = 3000
σ = 300
n = 30
(3500 - 3000) ÷ (350/√(30))
Test statistic = 7.824
Df = 30 - 1 = 29
Tcritical at 0.01 = 2.462
Test statistic > critical value ; we reject H0 ; and concluded that there is significant evidence that
μ ≠ 3000
