Y-18=14
Well, to start off, what is y?
Move 18 to the other side
y-18=14
+18+18
thus,
y=32
Then just plug n chug, into the second equation
3(32+5)
distribute the 3
3*32=96
3*5=15
then add what you have multiplied out
96+15=111
Thus, the value of 3(y+5)= 111.
Answer:
220 cents, $2.20
Step-by-step explanation:
Count the amount of QUARTERS there are.
7 quarters.
The next coin in the photo is a dime.
4 dimes.
The next coin in the photo is a penny.
5 pennies.
Quarters are worth 25 cents, dimes are worth 10 cents, and pennies are worth 1 cent.
25(7) + 4(10) + 5(1) = v (the total value)
25 * 7 = 175 cents
4 * 10 = 40 cents
5 * 1 = 5 cents
175 + 40 + 5 = v
175 + 40 = 215 cents
215 + 5 = 220 cents
The value of all of those coins is 220 cents, or $2.20.
Answer:
4 ducks
12 chickens
Step-by-step explanation:
Ducks to Chicken (ducks : chicken) ratio
= 1 : 3
Ducks to Chicken ratio, if chickens = 12
= ? : 12
1 : 3 = ? : 12
Find the scale factor of the ratios by dividing the number of chickens to the ratio of chickens.
12 ÷ 3 = 4
To find the number of ducks, multiply the ratio of ducks by the scale factor.
1 X 4 = 4
Therefore, there are 4 ducks and 12 chickens on the farm.
Ratios can also be written like fractions. Use this to check the answer:
1/3 = 4/12
4/12 can be reduced by dividing both the top and the bottom by 4.
4/4 = 1 Same as original ratio top
12/4 = 3 Same as original ratio bottom
Answer:
w = -12
Step-by-step explanation:
w/6 + 5/8 = -1 3/8
Subtract 5/8 from each side
w/6 + 5/8-5/8 = -1 3/8 - 5/8
w/6 = -1 3/5 - 5/8
w/6 = -1 8/8
w/6 = -2
Multiply by 6 on each side
w/6 *6 = -2*6
w = -12
Answer:
B=9
Step-by-step explanation:
Solve for b by simplifying both sides of the equation, then isolating the variable.
Hope this helps
