Answer:
Jada should have multiplied both sides of the equation by 108.
Step-by-step explanation:
The question is incomplete. Find the complete question in the comment section.
Given the equation -4/9 = x/108, in order to determine Jada's error, we need to solve in our own way as shown:
Step 1: Multiply both sides of the equation by -9/4 as shown:
-4/9 × -9/4 = x/108 × -9/4
-36/-36 = -9x/432
1 = -9x/432
1 = -x/48
Cross multiplying
48 = -x
x = -48
It can also be solved like this:
Given -4/9 = x/108
Multiply both sides by 108 to have:
-4/9 * 108 = x/108 * 108
-4/9 * 108 = 108x/108
-432/9 = x
x = -48
Jada should have simply follow the second calculation by multiplying both sides of the equation by 108 as shown.
Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180°
15x + 3 + 3x - 1 + 52 = 180
15x + 3x + 3 - 1 + 52= 180
Combine like terms.
18x + 54 = 180
To find the vlaue of x, we have to islolate x
<u>Step1:</u> Subtract 54 from both sides
18x = 180 - 54
18x = 126
<u>Step2:</u> Divide both sides by 18
x = 126/18
x = 7
Answer:
You can afford $1,000 per month as a house payment.
You can get a home loan at 5.3% interest for 15 years (paid monthly).
Then, after 15 years, the price of house that you can afford would be:
A x (1 + (5.3/100)/12)^(12 x 15) = 2.2 x A
With payment of 1000$ per month in 15 years, then we have
2.2 x A = 1000 x 12 x 15 = 180000
=> The price of house that you can afford now, would be:
A = 180000/2.2 = 81818.2$

Answer:
It is similar by AA
Step-by-step explanation:
AA stands for angle-angle. In similar figures, angles are congruent, and the sides are proportional. the corresponding angles are the same. Hope this helps!
