2b + 3s = 9.25, 3b + 4s = 13.25
Answer:
S=1.25
Step-by-step explanation:
If this is confusing pls let me know!! :) (p.s. sorry bout my handwriting lol)
A simple run down of the problem I guess is that first you need to solve one equation for either s or b. I chose the first equation to solve for b and I got b=(-3/2s)+(9.25/2). Then, the second thing you need to do is to put the answer to b in the second equation. This would be 3((-3/2s)+(9.25/2))+45 = 13.25. Then you basically solve that equation for s and you should get s=1.25. If you need to also find b you can plug s=1.25 into either of the starting equations. All done :) sorry this took long lol
Ans: The answer of your question is S=1.25

Answer:
3√512 = 8
Step-by-step explanation:
Step 1: Find the prime factors of 512
512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2
Step 2: Pair the factors of 512 in a group of three, such that they form cubes.
512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)
512 = 23 × 23 × 23
Using the law of exponent, we get;
512 = 29 [am.an = (a)m+n]
Or
512 = (23)3 [(am)n = amn]
512 = 83
Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.
3√512 = 3√(83)
So, here the cube root is eliminated by the cube of 8.
Hence, 3√512 = 8

Answer:
Number 3/ letter C
Step-by-step explanation:
Someone please help at your earliest convenience I would really appreciate it.
Answer:
Step-by-step explanation:
Let the equation is, y = x² + bx + c
Here, b = Sum of the roots
And c = multiplication of the roots
Roots of the equation are (5 + 2i) and (5 - 2i).
Step 1,
Sum of the roots 'b' = (5 + 2i) + 95 - 2i)
b = 10
Step 2,
Multiplication of the given roots = (5 - 2i)(5 + 2i)
= 5² - (2i)²
= 25 + 4
= 29
Step 3
Therefore, equation of the quadratic function will be,
y = x² + 10x + 29
Jada's parents purchase furniture for their new home. They buy 2 couches for $677 each, 4 beds for $465 each, and 3 lamps for $94 each. They decide to pay for all of the items in 4 equal payments. How much is each payment? $
Answer
$850.50
I think
Step-by-step explanation:
Answer:
874
Step-by-step explanation:
Couches: 2 × 677 = 1,354
Beds: 4 × 465 = 1,860
Lamps: 3 × 94 = 282
1,354 + 1,860 + 282 = 3496
Four equal payments: 3496 ÷ 4 = 874
Daniel solves the equation 3(x + 1) - 5 = 3x - 2 and states that it has no solution Is he correct? Explain why or why not
Erin wants to raise her math grade to a 95 to improve her chances of winning a math scholarship. Her math average for
the last marking period was an 81. Erin decides she must raise her math average by 15% to meet her goal. Do you
agree? Why or why not? Support your written by writing out your work. plz help 50 point
Answer:
There's a very simple way to solve this kind of problem. All we have to do is change the percent to a decimal and multiply it by her current grade.
81 × .15 = 12.15
For our purposes, we'll just round it down to 12. But anyway, raising her grade by 15% would mean raising it by 12 points.
81 + 12 = 93
This would give her an average of 93, not 95. She'd need to raise her grade 18% from 81 to get to her goal.

Answer:
i have a simple hack for this
Step-by-step explanation:
fyou see how theres a line? yes so act as if the 2 parts arent together just do 8x5x22 which equals 880 then do 8x5x12 which equals 480 then we add them together because the shapes were originally together so we do 880+480 which gets us to 1360

What is an equation of the line that passes through the points (1,1) and (7,-5)
I’ll give you BRAINLEST
Answer:
y=-x+2
Step-by-step explanation:
m=(y2-y1)/(x2-x1)=(-5-1)/(7-1)=-6/6=-1
y-y1=m(x-x1)
y-1=-1(x-1)
y-1=-x+1
y=-x+1+1
y=-x+2
Answer:
y=-1x+2
Step-by-step explanation:
m=
-5 - 1 over 7 - 1
(1,1). y=mx+b or 1=-1 × 1+b, or solving for b: b=1-(-1)(1). b=2.
(7,-5). y=mx+b or -5=-1 × 7+b, or solving for b: b=-5-(-1)(7). b=

13x + 15=17x-13 solve for the solution
Answer: x=7
Step-by-step explanation:
Step 1: Subtract 17x from both sides.
13x+15−17x=17x−13−17x
−4x+15=−13
Step 2: Subtract 15 from both sides.
−4x+15−15=−13−15
−4x=−28
Step 3: Divide both sides by -4.
−4x/−4 =−28/−4
x=7
