Answer:
Number of ice cream cones = 65
Number of sundaes = 49
Step-by-step explanation:
Let
x = number of ice cream cones
y = number of sundaes
x + y = 114 (1)
2x + 3.5y = 301.50 (2)
From (1)
x = 114 - y
Substitute into (2)
2x + 3.5y = 301.50 (2)
2(114 - y) + 3.5y = 301.50
228 - 2y + 3.5y = 301.50
- 2y + 3.5y = 301.50 - 228
1.5y = 73.50
y = 73.50/1.5
y = 49
Substitute y = 49 into (1)
x + y = 114 (1)
x + 49 = 114
x = 114 - 49
x = 65
Number of ice cream cones = 65
Number of sundaes = 49
the two lines below are parallel if the slope of the red line is 5 what is the slope of the green line
Answer:
5
Step-by-step explanation:
Since the two lines are parallel, they must have the same slope. This means that the slope of green line must be 5 just like the red line. You can also use the slope formula (rise/run) or change in y divided by change in x.
Help please! I don't really understand :/
I really really need your help!!
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

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.

5. Among the 50 pupils in a Grade 6 class, 6% are left-handed. How many are left-
handed?
1.
300 x 0.15 = 45
300 - 45 = 255
255 kids came to the party
//
2.
80 x 0.20 = 16
80 - 16 = 64
She got 64 items correctly
//
3.
50 x 0.28 = 14
50 - 14 = 36
36 pupils were present
//
4.
48 / 50 = 0.96
0.96 x 100 = 96.0%
96% joined the trip

“Solve for x, given that
Answer:
x = 20
Step-by-step explanation:
If angle PQS is = 70° then
x + 10 + 4x - 40 = 70 add like terms
5x - 30 = 70 add 30 to both sides
5x = 100 divide both sides by 5
x = 20

What is the solution set for StartAbsoluteValue 4 minus StartFraction x over 2 EndFraction EndAbsoluteValue = 8?
A.x = negative 24 and x = negative 8
B.x = negative 24 and x = 24
C.x = negative 8 and x = 8
D.x = negative 8 and x = 24
The solution to the set is .x = negative 8 and x = 24.
What is Absolute value?The separation of a number from a number line's origin is referred to as a number's absolute value. It is denoted by the symbol |a|, which specifies the size of any integer 'a'. Any integer's absolute value, regardless of its sign or whether it is positive or negative, will be a real number. The modulus of a, which is how two vertical lines |a| are used to symbolise it.
Given:
|4 - x/2| = 8
So, there are two possibilities
4- x/2 = 8 or 4 - x/2 = -8
-x/2 = 8-4 or -x/2 = -8-4
-x/2 = 4 or -x/2 = -12
x= -8 or x= 24
Hence, the solution to the set is .x = negative 8 and x = 24

8.6 x10^-9 in standard form
-9 in power means that the value is in fractional and the 10 base is multipied 9 times and put it on denominator.
8.6 = 86 x 10^-1
Let's multiply :
86 x 10^-1 x 10^-9
= 86 x 10^-10
= 86/10000000000
=0,0000000086
Note : if you don't know about how 10^-1 x 10^-9 returns 10^-10, it's because of exponential rules. If the base are same wuth each other, then just do the addition operation in the exponent like this :
10^(-1+(-9))
= 10^(-1-9)
=10^-10
