3x+4=7 solve equation with work.

Answers

Answer 1

X=1
3+4=7
3x1=3
3+4 =6 so X =1

Answer 2

Answer:

X=1

Step-by-step explanation:

reverse multiplication -

7=4+3x

we know one value so we just isolate the 3x

7-4=3, meaning that 3x has to be equal to 3.

Then we just do 3/3=1 so therefore x=1

Also if you wanna check it then you can plug x=1 into the equation.

4+3*x or 1=4+3=7

Hopefully this helped out, have a great day

Step-by-step explanation:

exponent means to multiply the number which has the exponent on it to itself like if 2 has the exponent 3 then that means 2 x 2 x 2

please make me the brainliest!

Elena is correct. Because the number 28 is smaller and above the number two, that means it is the exponent. The exponent, or the power, tells you how many times you multiply the number by itself. For example 2 to the 3rd power or 2 with a small 3 above it would be 2 x 2 x 2 which is 8 instead of 2 x 3 which is 6. I hope this helped you and good luck!

Step-by-step explanation:

Brenda pours laundry detergent from a bottle into the cap and then into the washing machine. Every time she fills the cap, the amount of detergent in the bottle changes by -0.26 liters. She fills the cap 3 1/4 times in all. John has a different bottle of detergent that is the same size. Every time he fills his cap, the amount of detergent in his bottle changes by -0.21 liters. He fills his cap 2 5/6 times in all. What was the total change for Brenda's bottle? What was the total change for John's bottle? Write as a decimal.

Answers

Brenda’s Bottle answer:

3 1/4 = 13/4 in improper fraction form.

13/4*-0.26 = -0.845. This is the difference in the change.

John’s Bottle answer:

2 5/6 = 17/6 in improper form

17/6*-0.21 = -0.595 in difference.
