14. This week, Anita spent 3 1/2 h practicing the piano. She also spent 6 1/4 h at soccer practice and 4 1/3 h on the telephone. a) How much time, in total, did Anita spend on the piano and at soccer? b) How much more time did Anita spend at soccer than on the phone?
this is fractions
Answer: a)9 3/4 hours
B)1 11/12 hour
Step-by-step explanation:
Piano: 3 1/2 hour; 3hours 30min
Soccer: 6 1/4 hour; 6hours and 15 min
Telephone: 4 1/3 hour; 4 hours and 20 min.
Remember that in an hour there is 60 min, and 1/2 of an hour is 30 (min), 1/4 is 15(min) and 1/3 is 20(min).
a) 3hours and 30min + 6hours and 15 min
That gives us 9 hours and 45 min, which is 9 3/4 hours.
B) 6hours and 15 min — 4 hours and 20 min
That gives us 1 hour and 55 min, which is 1 11/12 hours.

Two numbers have a sum of 1195 and a difference of 505?
Answer:
x = 850 and y = 345
Step-by-step explanation:
x + y = 1195
x - y = 505
Add the two equations
2x + 0y = 1700
2x = 1700
x = 850
Sub x = 850 into the first equation:
850 + y = 1195
y = 345
Thus, x = 850 and y = 345

Sheryl has a basket of ripe apples and peaches. The number of apples in the basket is 12 more than twice the number of peaches. If there are
36 apples in the basket, there are
peaches in the basket.
The number of peaches in the basket are 8.
What is equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Sheryl has a basket of ripe apples and peaches. The number of apples in the basket is 12 more than twice the number of peaches, there are 36 apples in the basket, there are peaches in the basket.
Let the number of apples be a and peaches be b,
Establishing the equations,
a-2p = 12
a = 12+2p.....(i)
a+p = 36.....(ii)
Using the equation (i) in equation (ii)
12+2p+p = 36
12+3p = 36
3p = 24
p = 8
Hence, the number of the peaches are 8.

Answer:
(x, y) = (2, 2)
Step-by-step explanation:
The graph is attached.
Both equations are in slope-intercept form:
y = mx +b . . . . . . line with slope m and y-intercept b
The graph of the first equation intersects the y-axis at +3, and has a slope (rise/run) of -1/2. That is, it decreases 1 unit for each 2 units to the right.
The graph of the second equation intersects the y-axis at -4, and has a slope of +3. It will increase 3 units for each unit to the right.
The point of intersection of the graphed lines is (2, 2).
The solution is (x, y) = (2, 2).

carys had some money. She brought a dirnk for £1.55 and a piece of cake for £1.30 she now has three-quarters of her money left. how much money did she have to start with?
Answer:
£11.40
Step-by-step explanation:
She spent £1.55 + £1.30 = £2.85.
Now she has 3/4 of the original amount.
That means she spent 1/4 of the original amount.
£2.85 is 1/4 of the original amount.
The original amount is 4 × £2.85.
She started with £11.40.
You can solve it by writing an equation.
She started with x.
x - 2.85 = 3x/4
x/4 = 2.85
x = 11.40

What's the slope
of a line parallel
to the line
3x - 5y = 7
Answer:
3/5
Step-by-step explanation:
The slope would be 3/5.
We can get the equation down to y=mx+b form first.
3x - 5y = 7
(Subtract 3x from both sides.)
-5y=-3x+7.
(Divide -5 on both sides.)
y=3/5-7/5.
Now, it is not parallel yet since to be parallel it needs a different y intercept, so just make one up.
Like:
y=3/5-7/3.
To see this visibly to make sure we can use desmos. com.
It is a graphing calculator where you can type the equation to see how it is graphed.
Answer:
m=3/5
Step-by-step explanation:
First rewrite the equation in slope intercept form. y=mx+b
[tex]y=\frac{-3}{-5} x-\frac{7}{5}[/tex]
The -3/-5 becomes positive.
[tex]y=\frac{3}{5} x-\frac{7}{5}[/tex]
In order to be parallel, use a different y value for "b."
Therefore, the slope is 3/5. Hope this helps and have a great day.

Answer:
b = 55°
Step-by-step explanation:
Angles around a point will always add up to 360°
Therefore, we can write an expression where we sum the 3 angles given and equate them to 360°:
(b - 15) + 3b + (2b + 45) = 360
eliminate the brackets and collect like terms:
b + 3b + 2b - 15 + 45 = 360
Combine like terms:
6b + 30 = 360
subtract 30 from both sides:
6b = 330
divide both sides by 6:
6b ÷ 6 = 330 ÷ 6
⇒ b = 55
Lea has 14coins that have a total value of $2.30. Coins are Nichols and quarters. How many of each coin does she have. Use substitution.
Answer:
Quarters = 8
Nickles = 6
Step-by-step explanation:
Call their numbers x and y.
The number equation is
x + y = 14
The value equation is
5x + 25y = 230
5x + 25y = 230-(5x + 5y = 70)
20y = 160
y = 8
x= 6
