3/4 (12x+8)=-13- (2x+3)
Answers
Answer: = − 2
Step-by-step explanation:
3/4 (12x+8)=−13−2x−3
Simplify 3/4(12x+8) to 3(12x+8)/4.
3(12x+8)/4=-13-2x-3
Factor out the common term 4.
3x4(3x+2)/4=-13-2x-3
Simplify 3×4(3x+2) to 12(3x+2).
12(3x+2)/4=-13-2x-3
Simplify 12(3x+2)/4 to 3(3x+2)
3(3x+2)=−13−2x−3
Simplify −13−2x−3 to −2x−16
3(3x+2)=−2x−16
Expand
9x+6=−2x−16
Add 2x to both sides.
9x+6+2x=−16
Simplify 9x+6+2x to 11x+6.
11x+6=−16
Subtract 6 from both sides.
11x=−16−6
Simplify −16−6 to −22
11x=−22
Divide both sides by 11.
x=− 22/11
Simplify 22/11 to 2.
x=−2

Gabriel is at the grocery store, and wants to figure out his total cost before he gets to the register. He bought 2.5 pounds of apples that are x dollars a pound and 2 bags of lettuce for y dollars each. Gabriel remembers he has a coupon for $2 off his bill.
Gabriel has $30 to pay for the groceries. What simplified expression would represent the amount of change he should receive
Answers
Answer:
32 - 2.5x - 2y
Step-by-step explanation:
He bought 2.5 pounds weight of apples for x dollars a pound. Thus, cost is 2.5x.
He bought 2 bags of lettuce for y dollars each. Thus, cost is 2y
Total bill cost = 2.5x + 2y
We are told he has a coupon for $2 off his bill.
This means the amount he will pay will now be;
2.5x + 2y - 2
Gabriel has $30 to pay for the groceries.
Thus, his change will be;
30 - (2.5x + 2y - 2)
This gives;
32 - 2.5x - 2y

m22 + m23 = 180°
m2l + m23 = 180°
Answers
Answer:
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.
Step-by-step explanation:
The correct question is attached.
Linear pairs angles are angles which are formed from the intersection of two lines and they are adjacent to each other. Linear pair angles are supplementary.
If angles are supplementary to the same angle, then they are congruent.
∠1 and ∠3 are vertical angles
∠1 and ∠2 form linear pairs while ∠2 and ∠3 form linear pairs. Therefore:
m∠1 + m∠2 = 180° (linear pair angles are supplementary)
m∠2 + m∠3 = 180° (linear pair angles are supplementary)
Hence using transitive property of equality:
m∠1 + m∠2 = m∠2 + m∠3
Using subtraction property of equality by subtracting m∠2 from both sides gives:
m∠1 = m∠3
∠1 ≅ ∠3 (vertical angles are congruent)
Because linear pairs of angles are supplementary. m∠1 + m∠2 = 180° and m∠2 + m∠3 = 180°.
Because angles that are supplementary to the same angle are congruent. It can be concluded that ∠1 ≅ ∠3.

Rearrange to make subject x 4(x-3)/a=y
Answers
Answer:
answer is x = ay + 12/4
Step-by-step explanation:
first we cross multiply on both sides which will give us this
4( x -3)=ay
we then open the brackets by multiplying 4 with x and -3 which gives
4x - 12= ay
then take 12 to the other side
4x - 12+12= ay + 12
4x = ay + 12
divide 4 on both sides
4x /4= ay + 12/ 4
therefore x = ay + 12/ 4

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it.
At the end of the 4 years, how much interest in dollars and cents did the account earn?
Answers
Answer:
$1105
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 6500 × 0.0425 × 4 = 1105
I = $ 1,105.00
The simple interest accumulated
on a principal of $ 6,500.00
at a rate of 4.25% per year
for 4 years is $ 1,105.00.
The area of a rectangular field is 48m2 and one of its sides is 6m . How long will a lady take to cross the field diagonally at the rate of 20m/min
Answers
Answer:
It will take her approximately 28 seconds to cross the diagonal of the pitch
Step-by-step explanation:
If we can find the length of the diameter of the field (in Metres), we can easily find the time it takes her to cross this length using motion equations.
Step one: Find the length of the field from its area.
The field is rectangular in shape. The area of the field is 48m^2. To get the area of the field, we had to multiply its length and its breadth.
i.e area = length X breadth.
Let us assume that the breadth = 6m
its length will be area / breadth = 42/ 6 = 7m
The length of the pitch = 7 m
Step Two: Find the length of the diagonal using Pythagoras' theorem.
From Pythagoras'theorem, the length of the diagonal can be obtained by
[tex]diagonal = \sqrt{l^2 +b^2}[/tex]
[tex]diagonal = \sqrt{6^2+ 7^2} = 9.22m[/tex]
The length of the diagonal is 9.22m
Step three: Find the time using her speed and the distance she needs to cover.
Time = distance / speed
time = 9.22 /20 = 0.46 minutes
It will take her approximately 28 seconds to cross the diagonal of the pitch
