Answer:
x=0 y=2
Step-by-step explanation:
2x+3y=6 .... 1
-5x+2y=4 .... 2
Multiply 5 with equation 1 and multiply 2 with equation 2
Then we get
10x+15y=30
-10x+4y=8
-10x and +10x get canceled so 19y=38
y=38/19=2
substitute y value in equation 1 or 2 and find the value to get x

A 12ft. tall ladder is leaning against a building. If the bottom of the ladder is 3ft. from the base of the building how high up the side of the building does the ladder reach? Put your answer in the box. Round your answer to the nearest whole number.
Step-by-step explanation: The Pythagorean theorem states that, in a right triangle, the length of the hypotenuse squared equals the sum of the squares of the other two sides or legs of the triangle. Algebraically, a2+b2=c2. In your example, the length of the ladder would be the hypotenuse and the distance from the wall would be one of the legs. So substitute these values into the equation to get: 32+b2=122 or 9+b2=144 and then subtract 9 from both sides to get b2=135. Therefore b=√135≈11.62. If your problem requires an exact answer in its most simplified form, please note that √135=3√15. Hope this helps you
Taylor had $60 dollars to buy a new pair of sneakers. He saw a pair he really liked that originally cost $72 but were on sale for 15% off. Does Taylor have enough money to buy them on sale?
Answer:
No.
Step-by-step explanation:
72 times 0.15=10.8
72-10.8=61.2
No. Taylor doesn't have enough.
You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.
Hope this helps!

Eighty percent of the picture frame is glass. A photo shows a picture frame of length 10 and three-fourth inches and width 8 and one-half inches, hanging on the wall. The border of the frame is labeled molding. What is the area of the molding?
Answer:
91.4 inches
Step-by-step explanation:
I will leave the explanation in the comments.
The area of the moulding is; 18 and 11/40 square inches
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
Here, we want to get the area of the moulding
we are given that the 80% of the frame is a glass photo
Means 20% of the picture frame will be that of the moulding.
By calculating 20% of the area of the frame, we get the area of the moulding;
43 /4 x 17/2 = 731/8
we have this as;
731/8 divided by 5
= 18 and 11/40 square inches

Answer:
19: The difference between the temperature in Fair Banks and Barlow is 3°F
20: -13°F, -10°F, 15°F, 24°F.
Step-by-step explanation:
I'm assuming that by "compare", it means to find the difference between temperatures in question 19. If it means something else, let me know and I'll try and help you find it.
Answer:
for 19 is the difference between the temperature in Fairbanks and Barlow is 3°F and for 20 is -13°F, -10°F, 15°F, 24°F.
it means to find the difference between temperatures in question 19 i guess that helps. 0-o

Mikey solved the inequality problem below incorrectly. Explain her error and redo the problem showing the correct answer.
Original problem: -4x+8<32
Mikey’s math work: -4x+8-8<32-8
-4x÷-4<24÷-4
x<-6
Answer:
Question 1: add 3a + 4a becuase they have the same variables. you should get 7a. Then subtract 10b and 4b because they have the same variables,You should get 6b. The answer is 7a+6b because you can't do anything with those numbers because of their variables and how they are not the same.
Question 2: The answer is x=10. to get the answer move all terms not containing x to the right side of the equation and add as normal.
Question 3: The answer is -5. Steps: move the equation around so there is a 2 on both sides of the equation, should look like this: 2x= -12 +2. Then add -12 +2 = -10. Then divide each term by 2 and simplify, should look like this: 2x/2 = -10/2. Then cancel the comments factor which is 2 should look like this: x = -10/2. After divide x by 1. Then divide -10 by 2 which equals -5.
Question 4: The answer is m=6. First multiply 6x2=12 then multiply that by 2 which should get u 24 then divide 24 by 4 =6
Question 5: sry I dont understand :(
Answer:
1. 7a+6b because 3a+4a=7a and 10b-4b=6b
2. x=10 because you add 3 to the other side to cancel it out and 7+3=10
3. x=6 because
2*m=2m and 2*6=12
24-12=12 and 12/2=6

IF YOU DONT KNOW THE ANSWER DONT ANSWER!! ANSWER ALL QUESTIONS
Answer:
A, A, A, B, DStep-by-step explanation:
1.
P(A) = 1/6, P(B) = 1/2
P(A and B) = 1/6*1/2 = 1/12
2.
P(A) = 1/6
P(B) = 1/6
P(A and B) = 1/6*1/6 = 1/36
3.
P(A) = 2/6 = 1/3
P(B) = 1/3
P(A and B) = 1/3*1/3 = 1/9
4.
P(gold) = 4/7 for each
P(2 golds) = 4/7*4/7 = 16/49
5.
Remaining marbles:
2 white, 1 orange and 2 green. Total 5 marblesP(green) = 2/5
