Answer:
x = - 15
Step-by-step explanation:
[tex]\frac{x}{9}[/tex] + [tex]\frac{1}{3}[/tex] = - [tex]\frac{4}{3}[/tex] ( multiply through by 9 to clear the fractions )
x + 3 = - 12 ( subtract 3 from both sides )
x = - 15
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−15

How to solve by completing the square??
x^2 +8x=33
We are given the equation x² + 8x = 33, and we need to solve it from completing the square, for which we will be following the below steps
Step 1 :- First, notice, what's the coefficient of x², if it's 1, then proceed to step 2, if not then divide both sides by the coefficient of x²
[tex]{:\implies \quad \sf x^{2}+8x=33}[/tex]
Step 2 :- Here, we need to develop a whole square in both sides somehow, so we have the coefficient of x, so add the square of half of coefficient of x on both sides :
[tex]{:\implies \quad \sf x^{2}+8x+{\bigg(\dfrac82\bigg)}^{2}=33+{\bigg(\dfrac82\bigg)}^{2}}[/tex]
Simplify both sides now :
[tex]{:\implies \quad \sf x^{2}+8x+(4)^{2}=33+(4)^{2}}[/tex]
Step 3 :- So now, here LHS is in the form of a² + 2ab + b², so we can just replace it by (a + b)², and we will keep simplifying RHS
[tex]{:\implies \quad \sf (x+4)^{2}=33+16}[/tex]
[tex]{:\implies \quad \sf (x+4)^{2}=49}[/tex]
[tex]{:\implies \quad \sf (x+4)^{2}=(\pm 7)^{2}}[/tex]
Step 4 :- As, power on both sides is 2, so we can just equate the bases
[tex]{:\implies \quad \sf x+4=\pm 7}[/tex]
Step 5 :- Equating x + 4 to 7, will yield x = 3, and equating it to -7, will yield x = -11, so we are now left with
[tex]{:\implies \quad \boxed{\bf{x=-11,3}}}[/tex]
Can someone help me figure out angle a in this circle? thank you!
Answer:
[tex]m \angle a = 116 \degree[/tex]
Step-by-step explanation:
By inscribed angle theorem:
[tex]m \angle a = \frac{1}{2} \times m \widehat{(BD)} \\ \\ \implies m \angle a = \frac{1}{2} \times 232 \degree\\ \\ \implies \huge { \orange{m \angle a = 116 \degree}}[/tex]

Decide which other to give him prices is better and explain why. Storage locker A rents for $32/yd2 per month. Storage locker B rents for $1.58/ ft2 per week. Assume 1 month = 4 weeks. Which one is better and why.
Answer:
Locker B
Step-by-step explanation:
When you divide 32 by 3 you get 10.667. Then when you divide that by 4 you get $2.667/ft2 per week.
A company rents moving trucks for $45 plus $0.75 per mile. write an equation that relates the cost C and the miles driven, x. Calculate the cost of
renting a truck for one day, and driving it 110 miles.
The equation we would use here would be 45 + 0.75x = C
This is because we have a flat fee of $45 and you are being charged $0.75 per mile, so it depends on how many miles were driven.
To find out how much it would cost if it were to drive 110 miles, we simply put 110 in place of x;
45 + 0.75(110) = C
And now we solve!
45 + 82.50 = C
$127.50
Hope this helps!

The volume of the outsdie layer whose diameter is of 8 inches is 290 cubic inches.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that bowling ball has an outside layer, and an inner core
One type of bowling ball has a diameter of 8 inches
We have to find the volume of the outsdie layer
Radius of the ball is 4 inches.
Volume of sphere = 4/3πr³
=4/3×3.4×4³
=4/3×3.4×64
=290 cubic inches
Hence, the volume of the outsdie layer whose diameter is of 8 inches is 290 cubic inches.

Joel is selling a motorcycle for $2,535. He bought the
motorcycle two years ago and paid $4,721 for it. It depreciated
35% during the two years. Is he losing money or making money
on this sale?
18. Willa is buying flowers for a large garden project. She plans
Answer:
Joel is losing money.
Step-by-step explanation:
4,721-35%=?
First, convert the percentage into a decimal.
35%=35/100=.35
Then multiply 4721 by .35 which is 1652.35
At last, subtract 4,721 by 1652.35= 3068.65

The Davis family purchased a house last year. They put $20,000 towards a down payment and took out a $265,000 mortgage. Because it was a new home, all the repairs and maintenance were covered under the builder’s warranty, but the Davises want to budget this coming year for unexpected expenses. When estimating costs for home repair and maintenance, a good estimate is to budget 1% of the purchase price of a house. What would be a good yearly estimate of repairs and maintenance for the Davis family’s home? a. $28,500 b. $2,650 c. $2,850 d. $200
Answer:
2,850
Step-by-step explanation:
I'm not very good with percentages, so this may be incorrect, but 1 ℅ of the total purchase price would be 2850 because 1 ℅ is essential 0.01 x 285,000. 285,000 would be adding the down-payment to the mortgage.
