The sum of two numbers is 52. The greater number is 4 more than the smaller number. Which equation can be used to solve for the
Arisa [49]

Answer:

x+(x+4)=52

Step-by-step explanation:

Let's name the smaller number x.

The greater number would then be (x+4).

<em>The sum of two numbers means we are adding them together.</em>

<u>The equation we could then set up would be:</u>

x+(x+4)=52

<em>Now we can solve the equation to find the two numbers if needed.</em>

<u>Here is how:</u>

x+x+4=52

Combine like terms.

2x+4=52

Subtract 4 from both sides.

2x=48

Divide both sides by 2

x=24

The smaller number is 24.

24+4=28

The larger number is 28.

Show two ways to multiply 2/15 x 3/20. Then tell wich way is easier and justify your choice
Radda [10]

The easier way to multiply 2/15 by 3/20 will simply be by multiplying the numerators and denominators.

In order to multiply 2/15 x 3/20, we can simply multiply the numerator and the denominator. This will be

= 2/15 × 3/20

= 6/300

= 1/50

Also, in order to multiply the fractions, we can change them to decimal first. This will be:

= 2/15 × 3/20

= 0.133 × 0.15

= 0.01995

In conclusion, multiplying the numerators and denominators is easier and faster.

Even would be helpful if you just gave me the equation to solve it and I can do the rest. mart had a sale for labor day on DVD's
erastova [34]

x - price of a video tape

y - price of a DVD

\left\{\begin{array}{ccc}2x+3y=134\\x+5y=179&|\text{subtract 5y from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}2x+3y=134\\x=179-5y&|\text{substitute to the first equation}\end{array}\right\\\\2(179-5y)+3y=134\qquad\text{use distributive property}\\\\(2)(179)+(2)(-5y)+3y=134\\\\358-10y+3y=134\qquad\text{subtract 358 from both sides}\\\\-7y=-224\qquad\text{divide both sides by (-7)}\\\\\boxed{y=32}\\\\\text{Put the value of y to the second equation}\\\\x=179-5(32)\\\\x=179-160\\\\\boxed{x=19}
