To find the answer, we just simply use PEMDAS, which means:
Parentheses
Exponents
Multiplication
(and/or)
Division
Addition
(and/or)
Subtraction
Solve the problem in this order. Since no operations are in the parentheses, we can skip that. The first operation we will do is multiplication. I can't really explain multiplication here, but you hopefully already know it, so multiply -4.31 by 3.09. Although there are negatives and decimals, treat it as a normal multiplication problem while doing the math.
This will give you -13.3179, just move the decimal point down, and since a positive is being multiplied by a negative, the answer is negative. Once you have this number, just add it to -0.98. This is the same as subtracting, since it is negative, so in other words, just subtract 0.98 from -13.3179, and you have your answer.
This would be -14.2979, or roughly -14.2.
Hope this helps! :)
Answer:
y=34x+2.625
y=34x+2.75
y=−34x+1.25
y=34x+1.25
y=−34x+2.75
Correct answer:
y=−34x+2.75
Step-by-step explanation:
Answer:
5/8
You put 625 over 1000 because it is in the thousandths place and then simplify
Answer:
Correct answer: x = - 3 and y = - 5
Step-by-step explanation:
Given:
2 x - y = - 1
3 x - 2 y = 1
We will multiply first equation with number (- 2) and get:
- 4 x + 2 y = 2
then we add this equation to another and get:
- 4 x + 3 x = 2 + 1
- x = 3 / · (- 1)
x = - 3
now we replace x = - 3 in the first equation and get:
2 (- 3) - y = - 1 ⇒ - 6 - y = - 1 / ·(- 1) ⇒ 6 + y = 1 y = 1 - 6 = - 5
y =- 5
God is with you!!!
