Answer:
C
Step-by-step explanation:
You just find the rate of change. So you would divide 30/1 which equals 30. So the equation is y=30x.
The answer is 7x = 6(x + 15)
x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours: 7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y
</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15
</span>7x = 6y
y = x + 15
Substitute the second equation into the first one:
7x = 6(x + 15)
Answer:” use
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal
Let x be the fluid ounces of milk does Monica use.
As per the statement:
Monica uses 3 tablespoons of milk in her custard recipe.
It is also given that:
The ratio of tablespoons to fluid ounces is 2 : 1.
by proportion definition we have;
by cross multiply we have;
3 = 2x
Divide both sides by 2 we have;
therefore, fluid ounces of milk does Monica use.”
Step-by-step explanation:
REAL BUT NOT RATIONAL :
square root of 2
the golden ratio : 1.618033.....non terminating
square root of 99
If you are asking 7/8 - 1/x= 3/4,
first put 3/4 to 6/8 to make it easier.
Move the 7/8 over to the right. You will get 1/x=-1/8.
Simplify, it is x=-8.
Check=7/8 - 1/8=6/8
It checks out.
