Lois is correct. This is because multiplication is repeated addition. It means that when your addends are just the same number but added several times, the sum is just equivalent to the product of that number times the number of times it was added. For example, 4+4+4 = 4×3 = 12.

What two consecutive integers equal 347.
zhannawk [14.2K]

Answer:

173 and 174

Step-by-step explanation:

Divide 347 by 2.

You get 173.5.

So, we can make the conclusion 173.5•2=347.

That is also equivalent to 173.5+173.5=347.

Subtract .5 from the first 173.5 and add it to the second 173.5, you can have

173+174=347.

So, the two consecutive integers 173 and 174 add up to 347.

What part of 5 and 3/4 is 7/10?
Effectus [21]

Answer:

7/10 is approximately 12.17% of 5 3/4.

To solve this, you'd first convert each value into a decimal.

7/10 - 0.70

5 3/4 - 5.75

Look at each value as a whole number. For example, if you wanted to find 3 of 8, you'd solve 3/8. The same principle applies here. If you were to type this into your calculator, you'd get 0.12173913043.

Next, convert the decimal (your quotient) into a percentage.

Remember, to convert a decimal to a percent, you have to multiply it by one hundred. So, .12173913043 would be 12.173913043.

After you convert, you can round to the nearest hundredth- that would give you 12.17%.

Check your answer:

To do this, you could multiply 5.75 by 12.17%, which would give you 6.99775.

You could then take this value and round it to 7.

Hope this helps,

6/2

= 3

slope intercept: −3x + y = −7

y - 9 = 5 (x - 1)
