What is the sum? -7 + 5 =sum

2 answers:

8 0

If one of the numbers you're trying to find the sum of is negative then do the following.

First, find the absolute values for both of the numbers then subtract the smaller amount from the larger amount. Then give the sign from the larger amount.

Find the absolute values of -7 and 5.

|-7| = 7
|5| = 5

Subtract 5 from 7.

7 - 5 = 2

7 is the larger number and it had a negative sign.

So, the answer is -2.

If there are twice as many bicycles as scooters and there are 945 vehicles in total. How many bicycles and scooters are there in

alexandr402 [8]

Answer:

Bicycles = 315

Scooters = 630, basic mathematics. The most effective method for these questions is substitution. But I might have intermingled them so double check

Which of the following pairs of numbers contains like fractions? A. 5⁄6 and 10⁄12 B. 3⁄2 and 2⁄3 C. 3 1⁄2 and 4 4⁄4 D. 6⁄7 and 1

ElenaW [278]

<h2>Hello!</h2>

The answers are:

$\frac{5}{6}$ and $\frac{10}{12}$

$\frac{6}{7}$ and $1\frac{5}{7}$

To find which of the following pairs of numbers contains like fractions, we must remember that like fractions are the fractions that share the same denominator.

We are given two fractions that are like fractions. Those fractions are:

Option A.

$\frac{5}{6}$ and $\frac{10}{12}$

We have that:

$\frac{10}{12}=\frac{5}{6}$

So, we have that the pairs of numbers

$\frac{5}{6}$

and

$\frac{5}{6}$

Share the same denominator, which is equal to 6, so, the pairs of numbers contains like fractions.

Option D.

$\frac{6}{7}$ and $1\frac{5}{7}$

We have that:

$1\frac{5}{7}=1+\frac{5}{7}=\frac{7+5}{7}=\frac{12}{7}$

So, we have that the pair of numbers

$\frac{6}{7}$

and

$\frac{12}{7}$

Share the same denominator, which is equal to 7, so, the pairs of numbers constains like fractions.

Also, we have that the other given options are not like fractions since both pairs of numbers do not share the same denominator.

The other options are:

$\frac{3}{2},\frac{2}{3}$

and

$3\frac{1}{2},4\frac{4}{4}$

We can see that both pairs of numbers do not share the same denominator so, they do not contain like fractions.

Hence, the answers are:

$\frac{5}{6}$ and $\frac{10}{12}$

$\frac{6}{7}$ and $1\frac{5}{7}$

Have a nice day!

Point P lies on the line with the equation y-4=3(x-2). If the x-coordinate of P is 4, what is the y-coordinate of P

maw [93]

Let's start by tidying up that equation and put it into slope-intercept form (y = mx + b); from there, we can plug in coordinates.

$y - 4 = 3(x-2)$

Let's use the distributive property on the right side:
$y - 4= 3x - 6$

Now add 4 to both sides
$(y - 4) + 4 = (3x - 6) + 4$

Which simplifies to:
$y = 3x - 2$

Since that's the equation of our line, now we can plug in coordinates and see what it churns out.

We know that the x-coordinate of P = 4 so let's substitute 4 in for x and calculate the y-coordinate:

$y = 3(4) - 2$
$y = 12 - 2$
$y = 10$

So the y-coordinate for point P = 10
