When the ratio is 1:1, either is 1/(1+1) = 1/2 the total.
7x = 10
•Paula added 7 to 10, which was her mistake. To fix her mistake, she would have to divide by 7, instead of adding 7. The correct answer is 10/7.
Answer:
A=2.5
B=2
Step-by-step explanation:
A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.
We can compare the two sides using algebra.
4b+7=8b-1
Using simple methods, we can isolate b on a single side.
1+7=8b-4b
8=4b
b=2
From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.
2a = 2b+1
2a = 2(2)+1
2a=4+1
2a=5
a=2.5
Answer:
x = 8.3 is the value of x.
Step-by-step explanation:
Given:
Let Δ ABC be a Right angle Triangle at ∠ C = 90°
AB = x
BC = 6
m∠ B = 44°
To Find:
x = ?
Solution:
We apply Cosine Rule
{tex}\cos B = \frac{\textrm{side Adjacent to angle B}}{Hypotenuse} \\{/tex]
Substituting the given values we get
The value of x is
x = 8.3
First you do 3 to the 2nd power which is 9 then you just add 12+9+50= 71
