Answer:
16
Step-by-step explanation:
let the smaller no be x so the greater no is 8 + x
soln
8+x + x = 40
8 + 2x = 40
2x = 40-8
2x = 32
x = 32÷2
therefore x = 16
Answer:
16 and 24
Step-by-step explanation:
let the 2 numbers be x and y, x > y , then
x + y = 40 → (1)
x = y + 8 → (2) [ greater number 8 more than smaller ]
Substitute x = y + 8 into (1)
y + 8 + y = 40, that is
2y + 8 = 40 ( subtract 8 from both sides )
2y = 32 ( divide both sides by 2 )
y = 16
Substitute y = 16 into (2)
x = 16 + 8 = 24
The 2 numbers are 16 and 24

Answer:
726 ft
Step-by-step explanation:
The perimeter is the sum of the 4 sides, that is
x + x + 274 + x + 27 + x + 74 = 3279, that is
4x + 375 = 3279 ( subtract 375 from both sides )
4x = 2904 ( divide both sides by 4 )
x = 726

Traveling 10 meters in 1/3 of a second how fast was it going
Answer:
I guess he was traveling 30 meters every second.
(Which is pretty slow to be honest)
Step-by-step explanation:
This question doesn't really make sense since it says it right there he traveled 10 meters in 1/3 of a second. But I'm guessing that you want to find out how many meters per second.
Since 1/3 multiplied by 3 = 1
Then 10 multiplied by 3 = 30.
So, he traveled 30 meters every second.

-(7x – 6) = 2(3x – 5) – 5x ?
Take x= -6 and y=4 find i) x+y,
ii) (x-y ) –x
iii) x 2 + y 2 +2xy
Answer:
I think it's either -3 or 10
Answer:
I) -2
ii) -60
III) 4
Step-by-step explanation:
i) x+y = -6+4=-2
ii) (x-y)-x = (-6-4)-(-6)= -60
III) x^2+y^2+2xy = (-6)^2+4^2+2(-6)(4)= 4

Part A
Estimate the cost of each soccer ball. Write an equation and solve.
Part B
Find the exact cost of each soccer ball. Compare your answer to your estimate to check for reasonableness.
Answer:
The equation is 216/20= 10.8 so about 11 dollars each
Step-by-step explanation:
Part B 216/ 15= 14.40 14.4 and 10.8 both round down so this awnser is reasonable

Answer:
x=13
Step-by-step explanation:
The 2 angles are corresponding meaning that they are equal to each other so the equation is going to be
6x-3=5x+10
step 1 add 3 to each side
6x=5x+13
step 2 subtract 5x from each side
x=13
The cost of a sweater at a clothing store was $35. The sweater went on sale at a discount of 20% off the original price. What is the sale price of the sweater?
Answer:
$28
Step-by-step explanation:
First, we have to find 20% of 35.
We can do that by multiplying 0.20 by 35. (0.20 x 35)
After multiplying them, we get a product of $7.
Since the sweater went on sale and they took 20% off of the original price, we have to subtract $7 from the original price of $35. (35 - 7)
We can solve that to get us the discounted price of $28

Answer:
x = 1y = 4Step-by-step explanation:
In order to solve this problem, we must assume the given triangles are congruent.
__
Equating expressions for the hypotenuse, we have ...
10x = 2x +8
8x = 8 . . . . . . . . subtract 2x
x = 1 . . . . . . . . . . divide by 8
Equating expressions for the bottom legs, we have ...
y +2x = 10x -y
2y = 8x . . . . . . . . add y-2x
y = 4x = 4(1) . . . . divide by 2, substitute for x
y = 4
g(x) = 2x - 4
h(x)=x+2
Find (g - h)(-4)
=============================================
Work Shown:
(g-h)(x) = g(x) - h(x)
(g-h)(x) = (2x-4) - (x+2)
(g-h)(x) = 2x-4 - x - 2
(g-h)(x) = x - 6
(g-h)(-4) = -4 - 6
(g-h)(-4) = -10
--------------------
An alternative method:
g(x) = 2x-4
g(-4) = 2(-4)-4
g(-4) = -8-4
g(-4) = -12
h(x) = x+2
h(-4) = -4+2
h(-4) = -2
(g-h)(-4) = g(-4) - h(-4)
(g-h)(-4) = -12 - (-2)
(g-h)(-4) = -12 + 2
(g-h)(-4) = -10

Answer:
x = 26
Step-by-step explanation:
The sum of the measures of the angles in a triangle is 180°.
(2x)° +50° +(3x)° = 180°

Step-by-step explanation:
Alright so this problem is like that other one i did where line RQx2 is equal to line SU
First we set up an equation
x+3=x-2
because line RQ is only 1/2 of line SU we multiple its side by 2 to get the new equation of
x+3=2x-4
step 1 subtract each side by 2x
-1x+3=-4
step 2 subtract each side by 3
-1x=-7
divide each side by -1
x=7
Next we plug in x (7) so 7-2=5
line RQ=5
