let's say the number is 15 is a substract 13 I get 2 but let's take 15 again of I add one I have 16 so it's incorrect
Answer:
Not true
Step-by-step explanation:
If we subtract x from both sides we geet -13 = 1, which of course is FALSE.

Answer:
75.4m²
Step-by-step explanation:
The shape shown is a cylinder
The volume of a cylinder can be calculated using this formula:
[tex]V=\pi r^2h[/tex]
where r = radius and h = height
The cylinder shown has a radius of 2m and a height of 6m
Using this information we plug in the values into the formula
[tex]V=\pi 2^26\\2^2=4\\4\pi =12.56637\\12.56637*6=75.39822[/tex]
So the area of the cylinder is 75.39822
Our final step is to round to the nearest hundredth
The final answer would be 75.4m²
Find the value of x.
Answer:
The value of x is 70
Step-by-step explanation:
Here, we want to find the value of x
To do this, we are going to use one of the circle tangent relationships
we have this as;
24 = (118-x)/2
2(24) = 118-x
48 = 118-x
x = 118-48
x = 70

James adds vitamin drops to his fish tank to keep his fish healthy. If James
follows the instructions on the bottle of vitamins, how many capfuls should he add
to his 450-litre tank? (4 marks)
• 2 drops per 5 litres
of water
• 1 capful = 40 drops
Step-by-step explanation:
350/5=70 liters X 2 drops for every 5 liters=140 drops needed for the whole tank.
Since 1 cupful contains 40 drops, the we have this:
140 drops needed for the full tank/40 drops contained in one cup, or,
140/40=3 1/2=3.5 number of cupfuls needed for the full tank.
hopefully this helps

The difference of the two numbers is 1.Their sum is 23.find the numbers
Answer:
11 and 12
Step-by-step explanation:
The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.
x + y = 23
x - y = 1
Add the equations together
x + y + x - y = 23 + 1
2x = 24
x = 12
y = x - 1
y = 11

y = [tex]\frac{-5}{4}[/tex]x + 3
Step-by-step explanation:As shown in the graph, the line is a straight line. Therefore, the general equation of a straight line can be employed to derive the equation of the line.
The general equation of a straight line is given by:
y = mx + c or -------------(i)
y - y₁ = m(x - x₁) -----------------(ii)
Where;
y₁ is the value of a point on the y-axis
x₁ is the value of the same point on the x-axis
m is the slope of the line
c is the y-intercept of the line.
Equation (i) is the slope-intercept form of a line
Steps:
(i) Pick any two points (x₁, y₁) and (x₂, y₂) on the line.
In this case, let;
(x₁, y₁) = (0, 3)
(x₂, y₂) = (4, -2)
(ii) With the chosen points, calculate the slope m given by;
m = [tex]\frac{y_2 - y_1}{x_2-x_1}[/tex]
m = [tex]\frac{-2-3}{4-0}[/tex]
m = [tex]\frac{-5}{4}[/tex]
(iii) Substitute the first point (x₁, y₁) = (0, 3) and m = [tex]\frac{-5}{4}[/tex] into equation (ii) as follows;
y - 3 = [tex]\frac{-5}{4}[/tex](x - 0)
(iv) Solve for y from (iii)
y - 3 = [tex]\frac{-5}{4}[/tex]x
y = [tex]\frac{-5}{4}[/tex]x + 3 [This is the slope intercept form of the line]
Where the slope is [tex]\frac{-5}{4}[/tex] and the intercept is 3

A) 2.2p
B) 1.2p
C)0.8p
D)0.2p
Answer: C. 0.8p

What is sector of circle?A circle's sector is a pie-shaped portion made up of the arc and its two radii. At both ends of the arc, when a section of the circle's circumference (also called as an arc) and two of its radii meet, a sector is produced. A sector of such a circle resembles a piece of pizza or a pie in shape.
A circle ranks among the most ideal shapes in geometry. The simplest geometric shape is that of a circle's sector. It has a number of its own components. such as sector, segmentation, circumference, segment, and diameter. The area of the sector is 250 units².
Therefore, the correct option is option A.

Olivia download music for $1.89 per song. She has a credit on her account for $3. Which expression could be used to represent the cost of the music if Olivia downloads m songs?
Answer:
Answer 3 (1.89m - 3)
Step-by-step explanation:
Since we know that the price per song is $1.89, that is going to be the part of the equation that goes with the variable.
Since she has a 3 dollar credit, this will reduce the cost of whatever amount of songs she is buying by 3 dollars, which means the second part of the equation is -3. You have your answer, 1.89m - 3.

Ms. Geiger made 100 cupcakes. 60/100 were chocolate, 2/10 were vanilla, and the rest were red velvet. What fraction of the cupcakes were red velvet?
Answer:
2/10
Step-by-step explanation:
Ms. Geiger made 100 cupcakes.
a) Number of chocolate
60/100 were chocolate
= 60/100 × 100 = 60 chocolate cup cakes
b) Number of vanilla
2/10 were vanilla
Hence:
2/10 × 100 = 20 vanilla cup cakes
c) the rest were red velvet.
Number rod red velvet = 100 - (60 + 20)
= 100 - 80
= 20 velvet cupcakes
What fraction of the cupcakes were red velvet?
Converting to fraction
Number of velvet cupcakes/Total number of cakes
= 20/100
= 2/10
Ellie is interested in getting a new phone. One phone company, phone 1 charges a monthly fee of 6$. They also charge 0.10$ per minute. Another company, phone 2, charges 5$ for a monthly fee and 0.25$ per minute. Write an equation for the total cost of each phone bill, where y is the total cost and x is the total number of minutes on the phone. Which company will allow Ellie to talk the longest is she only wants to spend 22$ a month
Answer:
Phone 1 will allow Ellie to talk the longest
Step-by-step explanation:
Phone 1:
(0.10x) + 6 = y
(0.10x) + 6 - 6 = 22 - 6
0.10/0.10x = 16/0.10
x = 160 minutes
Phone 2:
(0.25x) + 5 = y
(0.25x) + 5 - 5 = 22 - 5
0.25/0.25x = 17/0.25
x = 68 minutes
