Answer:
Then the two numbers are -11 and -6.
Answer:
11 and 6
Step-by-step explanation:
x+ y = 17 or y = 17-x
and
xy = 66 sub in y = 17-x
x ( 17-x) = 66
-x^2 + 17x - 66 = 0 either factor this, or use quadratic formula to find
x = 6 y = 11
two tenths plus blank equals forty nine hundredths

d
ninety eight hundredths
Answer:
b blank = 29/100
Step-by-step explanation:
2/10 + blank = 49/100
blank = 49/100 - 2/10
We need a common denomonator of r10 and 100. We can use 100.
blank = 49/100 - 20/100
blank = 29/100

What is the solution to the system of equations below?
y = negative 3 x + 5 and y = 4 x minus 2
Answer:
(1, 2)
Step-by-step explanation:
Since we are finding a solution that matches both equations, y = -3x + 5 is equal to y = 4x - 2.
So -3x + 5 = 4x - 2
Then group terms like so by moving them to the other side:
5 + 2 = 4x + 3x
7 = 7x.
Therefore x = 1.
Now to find y we substitue the value of x into an equation that contains y:
Y = 4x - 2
{x = 1}
Y = 4 - 2
Y = 2
Therefore the solution is (1, 2)

Find the surface area of the cylinder. Type an exact answer in terms of pi.
Answer:
154π cm²
Step-by-step explanation:
Radius (r) = 7 cm
Height (h) = 4 cm
Surface area of cylinder
= 2πr (h + r)
= 2π (7) (4 + 7)
= 2π (7) (11)
= 2π (77)
= 154π cm²
______
Hope it helps ⚜
Answer:
154π cm²
Step-by-step explanation:
Formula for the Surface Area of a Cylinder
SA = 2πr (h + r)Solving
Here r = 7 cm and h = 4 cmSA = 2πr (h + r)SA = 2π × 7 (7 + 4)SA = 14π × 11SA = 154π cm²hi! I hope that I can get the answer
Answer:

In a school 50% of learner's are younger than 10 , 1/20 are 10years old and 1/10 are older than 10 but younger than 12, the remaining learner's are 12 years old . If there are 400 learner's in the school ,how many learner's are there in each age group?.
Answer:
1/20=10 years old
In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. How many students are 10 years old?
50%= younger than 10
1/20=10 years old
1/10=older than 10 younger than 12
70=12 years or older
50%- 10/20
1/20-1/20
1/10-2/20
10/20+1/20+2/20=13/20
70 students =7/20
1/20 = 10 years old.
7/20 divided by 7 = 1/20
70 divided by 7=10

5 I bought 5 boxes of
crackers using a
coupon for 20% off. My
total bill was $6. What was
the original price of one
box of the crackers?
Answer:
1.20 x .2 which is the percent is $6. so the answer is $1.20
The original price of one box of crackers was $1.5 as per the concept of percentage.
Let's assume the original price of one box of crackers is "x" dollars.
After applying the 20% off coupon, you paid 80% of the original price for each box.
So, the discounted price of one box of crackers is 0.8x dollars.
Since you bought 5 boxes of crackers at the discounted price, the total bill becomes:
Total bill = 5 × 0.8x
Total bill = 4x dollars
Given that the total bill was $6, we can set up the equation:
4x = 6
Now, we solve for "x":
x = 6 / 4
x = 1.5
So, the original price of one box of crackers was $1.5. Before the discount, each box cost $1.5, but with the 20% off coupon, you paid 80% of the original price, which resulted in a total bill of $6 for 5 boxes.
