Answer:
Step-by-step explanation:
35 a + 34 b = 163.50 (given)
15 a + 17 b = 76.50 (given) multiply this equation by -2
-30 a - 34 b = -153.00 now add this equation to the first equation t get
5 a = 10.50 solve this for a (apple's price) then sub this value into one of the equations to find banana price, b.

12=6-90
asap please xoxo!!!!!!
answer:
72
step-by-step explanation:
your question doesn't make mathematical sense how can 12 = 6 then subract 90?
maybe you meant 12 + 6 - 90
if so
the answer is
72
(my work)
12 + 6 = 18
18 - 90 = 72
hope this helped <3
What is -5n+7<57 and 6n+2<8
Answer:
if -5n+7<57, then n>-10.
if 6n+2<8, then n<1.
Step-by-step explanation:
-5n+7<57
1. subtract 7 from both sides:
-5n+7 -7< 57 -7
-5n<50
2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):
-5n ÷-5<50 ÷-5
n>-10
6n+2<8
1. subtract 2 from both sides:
6n+2 -2<8 -2
6n<6
2. divide both sides by 6:
6n ÷6<6 ÷6
n<1

Each pair of polygons is similar. Write a similarity statement for the polygons. Then, find the measure of x, the measures of the indicated sides, and the scale factor.
Answer:
C
Step-by-step explanation:
The similarity statement is correct. Because they are similar, AB is equal to EF, so to find x, you do x-2=2.2. Solve that and you get x=0.2

PLEASE ANSWER ASAP !!!!
please help me this, this is very urgent!! thank you so much!
Answer:
KPL= 64 degrees JPL= 116 degrees
Step-by-step explanation:
2x+24+4x+36=180
combine like terms
6x+60=180
6x=120
x=20
2(20)+24=64
4(20)+36=116
Pls help! I WILL GIVE YOU BRAINLEIST
Answer:
1) = 180 degree reason = being AB is a straight line or supplementary
2) = angle AOB reason = being all the angles are of a straight line AB
3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle
4) = 42 degree
1) fill 180° in the blank
Reason :
Because AOB angles is half a page so it equals 180°
_________________________________
2)fill 180° in the blank
Reason :
AOE + EOF + FOB = AOB
And we have found that AOB angles is half a page so it equals 180°
_________________________________
3) 2x + 34 _ 180°
_________________________________
4) x = 42°

Sarah has been keeping track of how many hours she practices basketball each week and thinks that the percentage of free throws she makes during practice improves the more she practices. To check this, she makes a graph comparing the number of hours she practices each week with the percentage of free throws she makes each week. based on what she learned in her algebra class, she realizes that her graph represents a function. Which of these could be sarah's graph?

Help me with (-6,-7);y=-4x+1
Answer: y=-4x-31
Step-by-step explanation:
To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.
-7=-4(-6)+b [multiply]
-7=24+b [subtract both sides by 24]
b=-31
Now, we know that y=-4x-31 is the equation.

6-4(a+2)=8+a
What dose a equal
Answer:
-2 =a
Step-by-step explanation:
6-4(a+2)=8+a
Distribute
6 - 4a - 8 = 8+a
Combine like terms
-2 -4a = 8+a
Add 4a to each side
-2-4a+4a=8+a+4a
-2 = 8+5a
Subtract 8 from each side
-2-8 = 8+5a -8
-10 = 5a
Divide each side by 5
-10/5 = 5a/5
-2 =a
Plzzz help
Solve v+8<3or -8v<-40
v < −5 or v > 5
We know either v+8<3 or −8v<−40
Possibility 1
v+8<3
v+8−8<3−8
Subtract 8 from both sides
v<−5
Possibility 2
−8v<−40
−8v −8 < −40 −8
Divide both sides by -8
v>5
-x^2+15x-44
factor the equation
Answer:
- (x - 4)(x - 11)
Step-by-step explanation:
Given
- x² + 15x - 44 ← factor out - 1 from each term
= - 1 (x² - 15x + 44) ← factor the quadratic
Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)
The factors are - 4 and - 11 , since
- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus
x² - 15x + 44 = (x - 4)(x - 11) and
- x² + 15x - 44 = - (x - 4)(x - 11)

Descartes' rule of sign is used to determine the number of real zeros of a polynomial function. It tells us that the number of positive real zeroes in a polynomial function f(x) is the same or less than by an even numbers as the number of changes in the sign of the coefficients.
