9. One number is 7 more than twice another number. The sum of the numbers is 22. What is one of the numbers?
O-5
O 10
07
O 17
Step-by-step explanation:
Hey there!
According to the question,
Let the unknown number be x (smaller) another number be y (greater) respectively.
1st condition: One number is 7 more than twice of another number.
(i.e y = 2x+7)....... (i)
2nd condition: The sum is 22.
(i.e X+y= 22)……(ii)
From equation (ii).
x+ y= 22
x= 22-y
Putting the value of X in eqaution (I)
y = 2(22-y)+ 7
y = 44 - 2y +7
3y = 44+7
y = 51/3
Therefore, y= 17.
Now, Putting the value of y in eqaution (ii)
X = 22-y
x = 22-17
Therefore, x= 5.
Therefore, one number is 17. (Option D).
Hope it helps....

QUESTION 2
Angle J is (7x+2) Angle L is (25x-14)
What is (x)
Answer:
UV=25 units
Step-by-step explanation:
we know that
UW=UV+VW -----> by addition segment postulate
substitute the given values
4x+10=5x+5
solve for x
5x-4x=10-5
x=5
Find the value of UV
UV=5x
substitute the value of x
UV=5(5)=25 units

Work our the surface area of this cylinder?
Answer:
[tex]A=522.97\ \text{cm}^2[/tex]
Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 8 cm
Radius, r = 4 cm
Height of the cylinder, h = 16.8 cm
We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :
[tex]A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2[/tex]
So, the surface area of the cylinder is [tex]522.97\ \text{cm}^2[/tex]
If x is the number of bags of M&Ms bought at $3 per bag, and y is the number of bags of Kit Kats
bought at $4 per bag, which expression represents the total amount spent on M&Ms and Kit Kats?
Answer:
3x+4y
Step-by-step explanation:
If you buy 2 M&Ms, you would get $6. Plugging in 2 for x would indeed give us 6, which makes sense.
If you buy 2 KitKats, you would get $8. Plugging in 2 for y would indeed give us 8, which makes sense.
Therefore, we can plug in x and y for the unknowns and add them together to find the total amount spent on both candies.

Step-by-step explanation:
Answer:
(3, 5)
Step-by-step explanation:
Use the equation already isolated and plug it into the other equation
3x + 2( x t 2)= 19
solve for x
3x + 2x +4 = 19
5x= 19-4
5x= 15
x= 15/5
x=3
Now plug x (3) into one of the equations to find y
y= 3 + 2
y= 5
Put it in (x, y) form, (3, 5)

7
f. y=.752
8. y= 2.332
hy=1.62
8.
Yeah
Answer:
The answer is below
Step-by-step explanation:
a) Let y represent the amount of time kiran slept, hence:
y = x - (1/10)x = x - 0.1x
y = 0.9x
b) Let y represent the amount of time Mia practice, hence:
y = x - (2/5)x = x - 0.4x
y = 0.6x
c) Let y represent the amount of drink kiran drank, hence:
y = x + (4/3)x = 7x / 3
y = 7x/3
d) Let y represent the money Mai spent, hence:
y = x - (1/4)x = x - 0.25x
y = 0.75x
e) Let y represent the amount of almond kiran ate, hence:
y = x + 1.5x = 2.5x
f) Let y represent the recycling Mai collected, hence:
y = x - (3/10)x = x - 0.3x
y = 0.7x
g) Let y represent the amount of km kiran walked, hence:
y = x + (3/8)x
y = (11/8)x
h) Let y represent the amount of puzzles mai completed, hence:
y = x + (3/5)x = x + 0.6x
y = 1.6x

Answer:
x = 4
x = 1
Step-by-step explanation:
hey there,
< When you have these kinds of problems:
[tex]\frac{2}{6} = \frac{x}{12}[/tex]
There's a really easy way to solve it. Multiply the two that are across from each other. That means 2 x 12. It couldn't be 6 x [tex]x[/tex] because this one has x in it so it won't work. So you multiply them: 2 x 12 = 24. Then you divide that number by the last number available. The last number that hasn't been used yet is "6" (we have used 2 and 12). So we divide 24/6.
24/6 = 4
x = 4 >
