Step-by-step explanation:
8x + y = -16
y = -8x - 16 --(1)
-3x + y = -5 --(2)
sub (1) into (2):
-3x - 8x - 16 = -5
-11x = 11
x = -1
sub x = -1 into (1):
y = -8(-1) - 16
y = -8
therefore, the solution is (-1, -8).

7. Sorry, I couldn't figure out how to solve this question :(
Step-by-step explanation:
Since I'll be using a similar method to solve these questions, I won't go into a detailed explanation for how I solved every single question. If you do need extra help, please ask in the comments below my answer.
1. Let's use part (a) as an example. The ratio is 3:10. To new ratio is ?:40. So, 10 becomes 40. What number multiplied by 10 equals 40? The answer is 4. If 10 is multiplied by 4, then 3 must be multiplied by 4 as well. 3*4 = 12, so the ratio is 12:40.
In part b the ratio is multiplied by 3, part c is 4, and part d is 1/2.
2. To solve this, add the values on both sides of the ratio together: 2 + 5 = 7. Now, divide the total number of pupils, 140, by 7: 140/7 = 20. Finally, multiply 20 by both sides of the ratio: 2 * 20:5 * 20 = 40:100. There are 40 boys and 100 girls.
3. To solve this I used the same method as the one I used in question 1.
4. The ratio is 5:140, where 140 becomes 2000. To solve, use the method used in question 1.
5. Simplifying ratios is the same as simplifying fractions. Find the greatest common factor of the values on both sides of the ratio and divide both sides by that factor. For example, in part a the factor for 45:20 is 5. 45/5 = 9 and 20/5 = 4. The ratio becomes 9:4.
For part b the factor is 9 and for part c the factor is 50.
6. Same method as was used in question 2.
Hope this helps :)
A fisherman can row upstream at 4 mph and downstream at 6 mph. He started rowing upstream until he got tired and then rowed downstream to his starting point. How far did the fisherman row if the entire trip took 7 hours?
Answer:
The fisherman row 14 mph
Step-by-step explanation:
downstream means to subtract so you subtract 6-4 which will gives you 2 then you multiply 2 times 7 which is 14 because it says hours.
Jessica is hiring a plumber to remodel her bathroom. She knows that this job will take many hours to complete, so she wants to find a plumber that costs less than
$50 per hour (not including the fee for coming out to her house). A number of plumbers submitted the cost of their most recent job. Which of the following
plumbers cost less than $50 per hour? Select two that apply.
O Pattie's Plumbing charged $400 for a 7 hour job. There is no fee to come to the house,
Shannon's Plumbing charged $370 for a 5.5 hour job. This includes an $80 fee to come to the house.
Axel's Plumbing charged $220 for a 4 hour job. This includes a $10 fee to come to the house.
Bill's Plumbing charged $180 for a 2 hour job. This includes a $100 fee to come to the house
Tyrese's Plumbing charged $280 for a 3.5 hour job. This includes a $120 fee to come to the house
OOOO
Answer:
B and E
Step-by-step explanation:
B. You subtract the & $120 from $280, then divide the sum by 3.5 hours you’ll get $45.71
E.you subtract the $100 from $180 and divide it by 2 hours you get $40
Bill's Plumbing charged $180 for a 2-hour job. This includes a $100 fee to come to the house
Tyrese's Plumbing charged $280 for a 3.5-hour job. This includes a $120 fee to come to the house
From the given question, we need to determine the plumber that costs less than $50 per hour.
For the first option, if Pattie's Plumbing charged $400 for a 7-hour job, the cost per hour will be $400/7 = $57.14/hr. This shows that the plumber cost more than $50 per hourFor the second option, If Shannon's Plumbing charged $370 for a 5.5-hour job, the amount she is making in an hour is 370/5.5 = $67.27. This shows that Shannon cost more than $50 per hourIf Bill's Plumbing charged $180 for a 2-hour job and this includes a $100 fee to come to the house, Bill's pay per hour will be (180-110)/2 = $35. This shows that Bill cost less than $50 per hourIf Tyrese's Plumbing charged $280 for a 3.5-hour job and it includes a $120 fee to come to the house. Tyrese's pay per hour will be (280-120)/3.5 = $45.7. This shows that Tyrese cost less than $50 per hour

Answer:
that gabiella needs to get life like what a brat
Step-by-step explanation:
“ Triangle A has side lengths 3,4 and 5 . Triangle B has side lengths 6,7 and 8 “
“1. Explain how you know that triangle B is not similar to triangle A”
“2. Give possible side lengths for triangle B so that it is similar to triangle A”
Answer/Step-by-step explanation:
A. Given that ∆A has side lengths 3, 4, and 5, that corresponds to the side lengths 6, 7, and 8 of ∆B, both ∆s can only be similar to each other if the ratios of their corresponding side lengths are equal.
Thus:
[tex] \frac{3}{6} [/tex] ≠ [tex] \frac{4}{7} [/tex] ≠ [tex] \frac{5}{8} [/tex] .
✅The ratio of their corresponding side lengths is not equal, therefore, triangle B is not similar to triangle A.
B. To get the possible side lengths for triangle B to make it similar to triangle A, simply multiply each side length of triangle A by a scale factor.
Let's use a scale factor of 2.
3 × 2 = 6
4 × 2 = 8
5 × 2 = 10.
✅Possible side lengths for triangle B that will make it similar to triangle A are: 6, 8, and 10.

How to find the value
Answer:
x = 4°
Step-by-step explanation:
According to exterior angle sum property , sum of two opposite interior angles of the triangle is equal to the exterior angle.
So, using exterior angle sum property :-
mBDC + mBCD = mWBC
=> 8x - 1 + 46° = 18x + 5
=> 18x - 8x = 46 - 1 - 5
=> 10x = 40
=> x = 4°

Write the slope intercept form of the equation of each line plz
Answer: B . y = 5/6x + 7
Step-by-step explanation:
5x - 6y = - 42 To write it in slope intercept form, we need to solve for y.
-5x -5x Subtract 5x from both sides
-6y = -5x - 42 Divide both sides by -6
y = 5/6x + 7
Joseph makes ornaments to sell at the craft fair. Each ornament requires 0.5 yards of velvet. At the fabric store, felt is sold by the foot. If Joseph wants to make 45 ornaments, how many feet of velvet must be buy? If the felt costs 10 cents ($0.10) per foot, what is the total cost of the velvet in dollars? A manufacture is making 1,000 times as many ornaments as Joseph to sell in stores nationwide. Write an expression using exponents to show how many yards of velvet the manufacture will need. Do not calculate the total.
Answer: See explanation
Step-by-step explanation:
A. Since each ornament requires 0.5 yards of velvet and Joseph wants to make 45 ornaments, the number of yards of velvet she must be buy will be:
= 45 × 0.5
= 22.5 yards
Since 1 yard = 3 feet
22.5 yards = 22.5 × 3 = 67.5 feet
B. If the felt costs 10 cents ($0.10) per foot, what is the total cost of the velvet in dollars.
Total Cost = 67.5 × $0.10 = $6.75
C. A manufacture is making 1,000 times as many ornaments as Joseph to sell in stores nationwide. The amount of yards needed will be:
= 1000(45 × 0.5)
