Question is: Solve -7(x+6)=4(x+6)

Answers

$\huge\boxed{x=-6}$

Hey there! Our goal here is to isolate the variable on one side of the equation.

$\begin{aligned}-7(x+6)&=4(x+6)&&\smash{\Big|}&&\textsf{Start with the original equation.}\n-7x+(-7)(6)&=4x+4(6)&&\smash{\Big|}&&\textsf{Distribute.}\n-7x-42&=4x+24&&\smash{\Big|}&&\textsf{Multiply.}\n-7x-4x&=24+42&&\smash{\Big|}&&\textsf{Move the terms.}\n-11x&=66&&\smash{\Big|}&&\textsf{Combine like terms.}\nx&=\boxed{-6}&&\smash{\Big|}&&\textsf{Divide both sides by $-11$.}\end{aligned}$

Answer: The answer is x=–6.

Step-by-step explanation: Step 1: Simplify both sides of the equation:

$(-7)(x)+(-7)(6)=(4)(x)+(4 )(6)$ (Distributive Property)

$-7x+-42=4x+24$

$-7x-42=4x+24$

Step 2: Subtract 4x by the both sides: $-7x-42-4x=4x+24-4x$

$-11x-42=24$

Step 3: Add 42 to the both sides: $-11x-42+42=24+42$

$-11x=66$

And step 4: Divide both sides by -11: $(-11x)/(-11)=(66)/(-11)$ , $x=-6$ .

A line has the equation y= 6x + 19 What are the coordinates of the y-intercept of the line

Answers

Answer:

coordinates of y- intercept = (0, 19 )

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 6x + 19 ← is in slope- intercept form

with slope m = 6 and y- intercept c = 19 or in coordinate form (0, 19 )

Answer:

4x²(x +6)

Step-by-step explanation:

The smallest coefficient, 4, is a factor of the largest, so that will be a common factor. All terms contain x to some power, the least of which is 2, so x² will be a common factor. Factoring those common factors out, we have ...

= 4x²(x +6)

The factor x+6 cannot be factored further, so this is the full factorization.

the Kelly family bought a new pet rabbit. They want to build an enclosure outside so it has lots of room to roam. They have 30 feet of leftover lumber to use. Find the length and width of the enclosure if the length is to be 4fteet longer than twice the width.

Answers

assume that since this is a simple math problem and they only mentioned legnth and witdth,
assume a perfect rectangle

so assuming they use all the lumber
30=perimiter
perimiter=legnth around=legnth+legnth+with+width

30=2legnth+2width
undistribute
30=2(legnth+width)
divide by 2
15=legnth+width
legnth is 4 more than 2width
legnth=4+2width
subsitute
15=legnth+width
15=4+2width+width
subtract 4
11=2width+width
divide by 3
11/3=width

legnth=4+2width
legnth=4+2 times (11/3)
lefnth=4+22/3
4=12/3
legnth=12/3+22/3
legnth=34/3 feet=11 and 1/3 foot

width=11/3=3 and 2/3

legnth=11 and 1/3 foot
width=3 and 2/3 foot

(a) 3x + 7y = 13, 5x + 2y = 12
How do i solve this linear equation using substitution method??

Answers

Answer:

x= 2, y= 1

Step-by-step explanation:

First label the 2 equations:

3x +7y= 13 -----(1)

5x +2y= 12 -----(2)

Make x or y the subject of formula for one of the equation so that we can substitute its value into the 2nd equation.

Here, I am making y the subject of formula in the 2nd equation.

5x +2y= 12

2y= 12 -5x

$y = 6 - (5)/(2) x$ -----(3)

Substitute (3) into (1):

$3x + 7(6 - (5)/(2) x) = 13$

Expand:

$3x + 42 - (35)/(2) x = 13$

Bringconstantstooneside:

$3x - (35)/(2) x = 13 - 42$

Simplify:

$- (29)/(2) x = - 29$

Multiplyby-2onbothsides:

$- 29x = - 58$

Divideby-29onbothsides:

x=2

Substitute x=2 into (1):

3(2) +7y= 13

7y +6= 13

7y= 13 -6 (-6onbothsides)

7y= 7

y= 7 ÷7

y= 1

A worker is paid $9.80 per hour, with time and a half for any hours over 40 per week. If he works 44 hours in a week, what will be his gross pay amount?a. $440.80
b. $450.80
c. $392.00
d. $406.70

Answers

b. 450.80

you multiply 40 x 9.80 ...equals 392.

take 1/2 of 9.80...that equals 4.90.
4.90 plus 9.80 equals $14.70 x 4 = 58.80

$58.80 plus 392. equals $450.80
