After inputting this graph into Desmos, it said that the slope was equal to -0.75
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.
5, 10 and 8 all need to equal the same number for it to be the exact same day. 5, 10, and 8 go into 40
Answer:
a^7/8^2
Step-by-step explanation:
Here, we want to write the expression using only positive exponents
An important rule for indices to use here is that;
a^-b = 1/a^b
thus;
8^-2 = 1/8^2
So we have;
1/8^2 * a^7
= a^7/8^2
Yes
Explanation: y = 6x + 2
y = x + 7
Combine the equation
6x + 2 = x + 7
Collect like terms
6x -x = 7 - 2
5x = 5
X = 1
Substitute x =1
Into any equation
y = 6(1) + 2
y= 6 + 2
y= 8
(1,8)
