In a deli the ratio of ham subs sold to cheese subs sold in a day was 9:4. If 36 cheese subs were sold how many ham subs were sold?
Answer:
oolollololollolollo
Step-by-step explanation:
The number of ham subs sold is given by the proportion equation A = 81
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number of ham subs sold be represented as A
Now , the proportion will be
The ratio of ham subs sold to cheese subs sold = 9 : 4
And , the number of cheese subs sold = 36
Substituting the values in the equation , we get
number of ham subs sold A / number of cheese subs sold = 9 / 4
On simplifying the equation , we get
A / 36 = 9 / 4
Multiply by 36 on both sides of the equation , we get
A = ( 9 x 36 ) / 4
A = 9 x 9
A = 81 ham subs
Therefore , the value of A is 81 ham subs
Hence , the number of ham subs sold is 81

6 blue slabs have a mean weight of 7 kg. 3 yellow slabs have a mean weight of 5 kg. 1 grey slab has a mean weight of 9kg. work out the mean of 10 slabs
Answer: 6.6kg
Step-by-step explanation:
6 blue slabs have a mean weight of 7 kg. The total weight of the 6 blue slabs will be:
= 6 × 7kg
= 42 kg
3 yellow slabs have a mean weight of 5 kg. The total weight of the 3 yellow slabs will be:
= 3 × 5kg
= 15kg
1 grey slab has a mean weight of 9kg.
To get the mean of the 10 slabs, we add their total weights together and divide by 10. This will be:
= (42kg + 15kg + 9kg)/10
= 66kg/10
= 6.6kg
Based on the information given the mean of 10 slabs is 6.6 kg.
Formulate
(9+5×3+6×7)/10
Calculate the quotient
9+15+6×7/10
9+15+42/10
Calculate the sum or difference
24+42/10
66/10
Reduce the fraction
33/5
Hence:
Mean=6.6 kg
Inconclusion the mean of 10 slabs is 6.6 kg.

what propery is 5(x + 3) = 35, then x + 3 = 7
Answer:
Property Used is Division Property of Equality
Step-by-step explanation:
We need to define the property used in solving 5(x + 3) = 35, then x + 3 = 7
The Division Property of Equality states that when we divide both sides of an equation by same non-zero number the two sides remain equal
So, in given question:
5(x+3)=35
Dividing both sides by 5 (Division Property of Equality)
5(x+3)/5=35/5
x+3=7
So, Property Used is Division Property of Equality

y = 1/3x - 4
Step-by-step explanation:
the line crosses the y-axis at -4
To calculate the gradient of a straight line we choose two points on the line itself. From these two points we calculate: The difference in height (y co-ordinates) ÷ The difference in width (x co-ordinates)
If we take the points (9,-1) and (6,-2), we do:
-1-(-2) = 1

Answer:
y = 1/3x - 4
Y- intercept = -4
Slope = 1/3
Step-by-step explanation:
Y intercept is where the line intercepts/passes through the y axis
Slope is how many units it takes HORIZONTALLY (side to side) to go up ONE unit VERTICALLY (up down)
It took the line 3 horizontal units to go up 1 vertical unit. So you divide 1 by 3 which gives you 1/3
Find the slope and y-intercept of the graph. y=5x-3
Answer:
Step-by-step explanation:
y=mx+b
your m is the slope and your b is the y-intercept
so for y=5x-3 your slope would be 5 and your y-intercept would be -3
The equation y = 5x - 3 represents a line with a slope of 5 and a y-intercept of -3.
How to Find the Slope and the Y-intercept of a Graph?The equation of a graph can be expressed as y = mx + b, which is in the slope-intercept form. This means that:
m is the slope
b is the y-intercept of the graph.
The line described by the equation y = 5x - 3 has a slope of 5, meaning that as x increases by 1, y increases by 5. The y-intercept, represented by the constant term -3, indicates that the line intersects the y-axis at the point (0, -3).
