Answer:
3/2 (or 1 1/2)
Step-by-step explanation:
-4 1/6 + 5 2/3 (express as improper fractions)
= -25/6 + 17/3 (convert fractions common denominator i.e 6)
= -25/6 + (17/3)(2/2)
= -25/6 + (17 x 2)/6
= -25/6 + 34/6
= 9/6
= 3/2
=1 1/2
Answer
• A. Equation: 25(5 + x) = 325
,
• B. Answer: 8 dogs
Explanation
Given
• Charge to wash a dog: $25.
• She washed 5 dogs on Saturday and then some more on Sunday.
• She made $325 for the weekend.
Procedure
She charges $25 per wash, she made $325 for the weekend, and we know that on Saturday she washed 5 dogs, but we don't know how many she washed on Sunday. Thus, we have to build an equation in which the number of dogs washed on Sunday is represented by x (as we do not know the real number).
Considering that the total money made has to be equal to the multiplication of the charge times the dogs washed, the equation is:
Then, we have to solve for x to know how many dogs did she wash on Sunday.
0. Multiplying the parenthesis
<em>2. Subtracting 125 from both sides of the equation</em>
<em>3. Dividing both sides of the equation against 25</em>
Answer:
y=0.3x
Step-by-step explanation:
Formula =
y α x
y = kx
Where k is the constant of proportionality.
When y = 1.5; x = 5;
We substitute these known values in the equation,
y = kx
1.5 = k5
Dividing both sides of the equation by 5 to find the value for k, we have
1.5/5= k0.3/5
Therefore,
K = 0.3
Having found the value of k,
We substitute this value into the relationship
y = kx
Therefore we have,
y = 0.3x.
The direct variation function is therefore,
y = 0.3x.

Answer:
The answer is 3.488
Step-by-step explanation:
Lets start from right to left.
we cant do 6-8 so we borrow from the place to the right which turns the 7 into a 6 and the 6 into a 16. 16 minus 8 is 8. Next 6-8 again (The seven is no more.) We already know we cant do dat soooo we borrow from the tenths place. The 1 is now a 0 and the 6 is now a 16. 16 minus 8 is 8. Next is 0-6 (No more 1 because we borrowed from the tenths place.) we cant do 0-6 so we have to borrow from the ones place. Make the 6 a 5 and make the 0 a ten. 10-6 is 4. So far we got 488 but make sure to add a decimal point in front of it. Always bring down the decimal point. so its now (.488) lastly 5- 2 is 3 so the answer is 3.488
9-3 because triple equals to 3. Mike has been studying for 9 years, so 9-3 with no = sign.
