Answer:
1.) 1/2x = 32
2.) 3x = 18
3.) x/7 = 4
4.) 5m=105
divide both sides by 5
m= 21
5.) -2c=-32
divide both sides by -2
c=16
6.) x/4=-44
multiply both sides by 4
x=-176
7.) s/-3 = -21
multiply both sides by -3
s=63

bring the 2 down.
5 divided by 12 is 2, 2 times 5 is 10, 12 minus 10 is 2
bring the 5 down.
5 divided by 25 is 5, 5 times 5 is 25,
bring the zero down.
5 divided by 0 is 0, 5 cannot go into 0.

There are 42 more red marbles in a jar than there are white marbles. If there are 238 marbles in the jar, how many of them are red and how many are white?
Answer:
Red: 161 White: 77
Step-by-step explanation:
Given there are 238 marbles in a jar, and there are 42 more red marbles than white marbles, we need to divide the number of marbles by two, as there are, presumably, two colors.
238 / 2 = 119
After doing this, we subtract 42 from one of the two 119s, and we add 42 to the other.
119 - 42 = 77
119 + 42 = 161
The value with 42 added is the red marble count, and the value with 42 subtracted is the white marble count.

Answer:
b = 22
Step-by-step explanation:
Here b represents the length of the hypotenuse, and 11 is the length of the side opposite the 30 degree angle. We want to find the value of b. We use the sine function here because we have the angle measurement (b), the angle 30 degrees and the "opposite side" 11:
sin 30 degrees = (1/2) = 11/b, which, if inverted, is 2 = b/11, or b = 22

8 / (x + 4) = 12 / (2x + 1) Cross multiply
8 * (2x + 1) = 12 * (x + 4)
16x + 8 = 12x + 48 Subtract 8 from both sides
16x + 8 -8 = 12x + 48-8
16x = 12x + 40 Subtract 12x from both sides
16x - 12x = 40
4x = 40 Divide by 4
4x/4 = 40/4
x = 10

Last month, Harri drove 850miles in his car. His car's fuel consumption is 45.6 miles per gallon petrol cost £1.09 per litre given that 8 pints=1 gallon work out how much Harri spent on fuel last month
Using proportions, it is found that Harri spent £76.91 on fuel last month.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using basic arithmetic operations, especially multiplication and division with the rates.
For this problem, we have that Harri drove 850 miles with a rate of 45.6 miles per gallon hence the number of gallons that Harri used is given as follows:
850/45.6 = 18.64 gallons.
Each gallon is equivalent to 3.78541 liters, hence the number of liters that Harri used is given as follows:
18.64 x 3.78541 = 70.56 liters.
The cost per liter was of £1.09, hence the amount that Harri spent during the last month is given as follows:
70.56 x 1.09 = £76.91.

Mina tiene \dfrac{4}{5} 5 4 start fraction, 4, divided by, 5, end fraction de la harina necesaria para hacer una hogaza. Se necesita la misma cantidad de harina para hacer 111 hogaza que para hacer 121212 panes. ¿Cuál es el mayor número de panes que Mina puede hacer con la harina que tiene?
Answer:
El mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.
Step-by-step explanation:
Una hogaza equivale a 12 torrejas de pan, si Mina tiene [tex]\frac{4}{5}[/tex] de la harina necesaria para preparar una hogaza. Entonces, el número total de torrejas es [tex]\frac{4}{5}[/tex] de 12 torrejas de pan. Es decir,
[tex]x = \frac{4}{5}\times 12[/tex]
[tex]x = 9.6[/tex]
Puesto que la cantidad de hogazas en un número entero, se trunca al entero más cercano. En consecuencia, el mayor número de panes que Mina puede hacer con la harina que tiene es 9 torrejas de pan.
Liz is watching a film at the cinema.
The film started at 1430
The film is 105 minutes long.
When the film ends, Liz takes 20 minutes to get to the bus stop.
A bus leaves the bus stop at 1645
Does Liz get to the bus stop in time to get this bus?
You must show all your working.
Answer:
Yes, she does
Step-by-step explanation:
105min=1h 45min
14h 30min + 1h 45min= 16h 15min
16h 15min + 0h 20min=16h 35min
16h 45min - 16h 35min= 10min
So, the answer is yes, she does and she still has 10 minutes free.
