Bec 4x-5
Answer:
x=11°
<Bec = 33°
<Ced = 39°
Step-by-step explanation:
That's a right angle so it would be 90 degrees angle.
18+3x+4x-5=90
Lets simplify it to make it easier to work out by collecting like terms.
First all the variable 3x+4x=7x
Then the numbers 18+-5=13
13(-13)+7x = 90(-13)take away 13 from both sides
(Opposite operators EG, Add becomes subtract)
7x = 77 then divide 7 from both sides
x=11
Then work out
3x11=33 degrees
4x11=44-5=39 degrees
To double check 39+33+18=90 degrees

Riley earned $38.25 for cleaning the garage. She was paid $4.25 per hour. Write and solve an equation to find how long it took her to clean the garage. Include a label in your answer.
Answers
Answer:
It took Riley 9 hours to clean the garage.
Step-by-step explanation:
With the information provided, you can say that the amount Riley earns for cleaning the garage is equal to the price per hour for the number of hours it takes to clean the garage, which can be express as:
x=4.25y, where:
x is the amount Riley earns for cleaning the garage
y is the number of hours it takes to clean the garage
Now, you can replace x with $38.25 that is the amount that Riley earned and you can solve for y to find how long it took her to clean the garage:
38.25=4.25y
y=38.25/4.25
x=9
According to this, the answer is that it took Riley 9 hours to clean the garage.
Given the line 2x + 3y = 5, write an equation for a line in slope intercept form that is parallel

O 15 x 2
Answers
Answer: [tex]15\times\frac{1}{2}[/tex]
Explanation:
Multiplying by 1/2 is the same as dividing by 2.
For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]
The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of which 20 were marked. To the nearest whole number, what is the best estimate for the turtle population?
Answers
Answer: 720
Step-by-step explanation:
From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.
If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:
1/20 × x = 36
x/20 = 36
x = 20 × 36
x = 720
The turtle population is 720

Answers
Answer:
6 * 10^2
Step-by-step explanation:
Simplify : (4.2×10^7)÷(7×10^4)
(4.2 × 10^7) / (7 × 10^4)
From indices : 10^a ÷ 10^b = 10^(a - b)
(4.2 / 7) * 10^(7-4)
0.6 * 10^3
= 6 * 10^2
Hence, (4.2×10^7)÷(7×10^4) = 6 * 10^2

After dilation of ΔABC, the length of B'C' = 8m and ∠A' = 28°.
What is Dilation?Dilation means changing the size of an object without changing its shape. The size of the object may be increased or decreased based on the scale factor.
When the triangle undergoes dilation, the length of its sides gets multiplied by 1/2 (dilation factor) but the angles remain the same ( since, the shape has to remain same).
