AB+AT=BT
(7Y+9)+(3Y+4)= 143
10Y+13= 143
10Y= 130
Y=13
AB= 7Y+9
AB= 7*13+9
AB=100

What is negative one eighth of a number is -3/4 as an equation?<br> will name the brainliest!
topjm [15]

Answer:

The equation is  -\frac{1}{8} x = -\frac{3}{4}

Step-by-step explanation:

The Equation is formed from two sides equal to each other

  • In the algebraic statement "is" means equal
  • In the algebraic statement "of" means times (×)

∵ One eighth means \frac{1}{8}

∴ Negative one eighth means  -\frac{1}{8}

→ Assume that the number is x

∵ "of" means times

∴ Negative one eighth of a number = -\frac{1}{8} × (x)

∴ Negative one eighth of a number = -\frac{1}{8} x

∵ Negative one eighth of a number is -\frac{3}{4}

→ "is" means equal, so the left side is -\frac{1}{8} x and the right side is -\frac{3}{4}

∴  -\frac{1}{8} x = -\frac{3}{4} ⇒ Equation

∴ The equation is  -\frac{1}{8} x = -\frac{3}{4}

How many solutions does the following system of equations have?
True [87]
We will use a method of substitution.
y = 5/2 x + 2 
2 y = 5 x + 4   ⇒  2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0            ⇒  x, y ∈ R
Answer: D)   
This system has infinitely many solutions.

Write 3/16 as a percent<br> A.) 6.25% <br> B.) 18.75<br> C.) 31.6<br> D.) 1875%
11Alexandr11 [23.1K]
Hello! Just by lookiing at the answer choices, we can eliminate D, because that percentage is just too big. What you would need to do is divide 3 by 16. 3/16 is 0.1875. Multiply that by 100 to get 18.75, which will be the percent, because percents are parts of 100. There. 3/16 is 18.75%. The answer is B: 18.75%.
