Answer:

5.352 or 5 352/1000

Step-by-step explanation:

Estimate the solution to the system of equations.
2x+3y=6
-4x+3y=12

Answers

The solution is:

$x=-1, y=2(2)/(3)$

Step-by-step explanation:

Given

2x+3y=6 Eqn 1

-4x+3y=12 Eqn 2

Subtracting equation 2 from equation 1

$2x+3y-(-4x+3y)=6-12\n2x+3y+4x-3y=-6\n6x=-6\nDividing\ both\ sides\ by\ -6\n(6x)/(6)=(-6)/(6)\nx=-1$

Putting x=-1 in equation 1

$2x+3y=6\n2(-1)+3y=6\n-2+3y=6\n3y=6+2\n3y=8\nDividing\ both\ sides\ by\ 3\n(3y)/(3)=(8)/(3)\ny=2(2)/(3)$

The solution is:

$x=-1, y=2(2)/(3)$

Answers

If Mrs Lopez drives a number of miles north. Then she drives 34 miles west. She drives 94 miles in all. The sentences to show how many miles she drives north will be 94=34+x.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, Mrs. Lopez drives a number of miles north. Then she drives 34 miles west. She drives 94 miles in all.

The sentences show how many miles she drives north is,

⇒94=34+x

⇒x= 94-34

⇒x=60

Thus, if Mrs. Lopez drives a number of miles north. Then she drives 34 miles west. She drives 94 miles in all. The sentences to show how many miles she drives north will be 94=34+x.

The math club has 57 members who are in sixth or seventh grades. There are twice as many sixth graders as seventh graders.

How many sixth graders are in the club?

A.
38

B.
37

C.
19

D.
18

Answers

A. 38

Let X = seventh graders

6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.

2X + X = 57
3X = 57
X = 57 / 3
X = 19

IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.

Add both numbers to check: 19 + 38 = 57.

Try 38. First divide 38 by 2, which equals 19. Then add 19 to 38 which will equal to 57. Hope this helps.

At the start of the week, you could run for 8 minutes. By the end of the week, you could run for 15 minutes. Which proportion could you use to find the percent increase in your running time?7/15=n/100

8/7=n/100

7/8=n/100

8/15=n/100

Answers

The formula for finding percent increase is:
(Final - Initial)/Final * 100 = n
Divide both sides by 100 and you get:
(final-initial)/Final = n/100
Plug in all the numbers, and you get:
(15-8)/15 = n/100, or
7/15 = n/100

Hope this helped!! :D

The answer to this is 7/8=n/100

What is 35/21 in lowest terms?

Answers

to simplify the fraction you must first find the number that goes into both numbers, in which is 7;

So divide both the numerator and the denominator by 7;

35 ÷ 7 = 5

21 ÷ 7 = 3

So your final answer would be;

35/21 = 5/3 = 1 2/3 (in simplest form)
