1. Solve the following equation.(MAFS.8.EE.3.7)

5(3x + 7) + 2x = 7x – 5(–2x + 9)

Answers

Answer:

there is no solution

Step-by-step explanation:

Expand.

15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45

2 Simplify  15x+35+2x15x+35+2x  to  17x+3517x+35.

17x+35=7x+10x-4517x+35=7x+10x−45

3 Simplify  7x+10x-457x+10x−45  to  17x-4517x−45.

17x+35=17x-4517x+35=17x−45

4 Cancel 17x17x on both sides.

35=-4535=−45

5 Since 35=-4535=−45 is false, there is no solution.

Your answer is: No solution (There are no values of  x  that make the equation true.)

A spinner is divided into sections of equal size, of which some are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 20%. The probability of the arrow landing on a section colored blue is 10%. What is the probability of the arrow landing on a section colored green?

Answers

The probability Would Be 1/5

Answer:

70%

What is given: 20% of one color, and 10% of another.

That gives us 30% of 100%.

Take away the smaller percentage from the limit, which would be 30 from 100.

You are left with 70%, which means that 20% is red, 10% is blue, and 70% is green.

Elliott is counting the change from a class fundraiser. He has half as many quarters as nickels, and he has 7 fewer dimes than nickels. The total value of coins is $5.90. He wrote the equation 0.10 (7 minus x) + 0.5 (x) + 0.25 (one-half x) = 5.90. Which statements identify Elliott’s errors? Check all that apply.
He should have written the expression for the number of dimes as x – 7.
He should have written the coin values as 5, 10, and 25 and not as 0.5, 0.10, and 0.25.
He should have written the coin value for the nickel as 0.05.
He should have translated the scenario as value of all dimes = value of all nickels and value of all quarters = value of all nickels.
He should have written the expression for number of nickels as 2x.

Answer:

Step-by-step explanation:

Move the decimal point in the divisor and dividend.

Turn the divisor (the number you’re dividing by) into a whole number by moving the decimal point all the way to the right. At the same time, move the decimal point in the dividend (the number you’re dividing) the same number of places to the right.

Place a decimal point in the quotient (the answer) directly above where the decimal point now appears in the dividend.

Divide as usual, being careful to line up the quotient properly so that the decimal point falls into place.

Line up each digit in the quotient just over the last digit in the dividend used in that cycle.
