Answer:
5 and 15
Step-by-step explanation:
Let x represent the smaller number. Then the larger is x+10. The sum is ...
2x +3(x+10) = 55
5x +30 = 55
5x = 25
x = 5
The two numbers are 5 and 15.

Check
2·5 + 3·15 = 10 +45 = 55
30(30-x)=540 what is the value of x
Answer:
x = 12
Step-by-step explanation:
Original equation:
30(30 - x) = 540
Use distributive property
30 · 30 = 900
30 · (-x) = -30x
Plug these values back into the equation
900 - 30x = 540
Subtract 900 from both sides
-30x = -360
Divide both sides by -30
x = 12

The probability that i will throw a six with a dice is
[tex] \frac{1}{6} [/tex]
what is the probability that I will not throw a six?
There are 6 numbers on a die. 5 numbers are not 6, so you have a 5/6 probability of not rolling a 6.
The answer is 5/6

which is closer to 0 3/8 or -1/3
Answer:
-1/3 is closer to 0
Step-by-step explanation:
3/8 is between 0 and -1/3. We need to determine if 3/8 is closer to -1/3 or closer to zero. Since -1/3 is smaller than 3/8, 3/8 is closer to -1/3. Since 3/8 is closer to -1/3, 3/8 rounded to the nearest -1/3 is -1/3.
9. Which is a solution of the equation 5(x – 8) = -55 ?
a) x = 3
b) x = 13
c) x = -3
d) x = -9.4
Answer: c. x = -3
5(x - 8) = -55
⇔ 5x - 40 = -55
⇔ 5x = -55 + 40 = -15
⇔ x = -15/5
⇔ x = -3

The points (0, -1) and (4,5) lie on the straight line L
Work out the gradient of L.
Answer:
gradient = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Calculate the gradient m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (4, 5)
m = [tex]\frac{5+1}{4-0}[/tex] = [tex]\frac{6}{4}[/tex] = [tex]\frac{3}{2}[/tex]

The length of rectangle A is 7.4 cm and the width is 4.8 cm. The perimeter of rectangle B is 14.9 cm. How much is the perimeter of rectangle A than the perimeter of rectangle B?
Answer: 9.5 cm
Step-by-step explanation:
First we have to find the perimeter of rectangle A:
Formula for perimeter of a rectangle or square is: [tex]2(a+b)[/tex]
Putting the length and width in: [tex]2(7.4+4.8)[/tex]
Solve it to get: 24.4 cm
Subtract 14.9 from 24.4 to get 9.5 cm

how is perimeter measured?
A)Using the metric system
B)Cubic units
C)Linear units
D)Units squared
Perimeter is the linear distance around an object.
It is measured in c) linear units
Perimeter is measured in linear units .
Given,
Perimeter
So,
Perimeter is the linear distance around an object.
For example,
Perimeter of circle is 2πr which means that the region which is considered is outer region along the radius of the circle and complete one circle that is 2π .
Similarly,
Perimeter of square is 4a that means the square is covered along its side 4 times that is along the sides of square .
Thus
