Step-by-step explanation:
Let x be the [number]
Rephrase the expression
2 times a number is increased by 4, it is the same as 25 decreased by the number
2x+4=25-x
Calculate
Given
2x+4=25-x
Add x on both sides
2x+4+x=25-x+x
3x+4=25
Subtract 4 on both sides
3x+4-4=25-4
3x=21
Divide 3 on both sides
3x/3=21/3
x=7

Daniel receives a 35% employee discount on all purchases he makes at the store. If he buys his brother a jersey that is regularly priced at $24.95, what price (before tax) will Daniel pay for the jersey?
ANSWER CORRECTLY AND I WILL GIVE YOU BRAINLIEST AND GET 10 POINTS
Answer:
The price to pay is $16.22
Step-by-step explanation:
From the question, the regular price is $24.95
now, there is a discount
So the price to pay is the regular minus the discount
Mathematically, we have this as:
24.95 - 35% of 24.95
= 24.95 - 0.35(24.95)
= $16.2175
This is approximately $16.22

Which of the following illustrates quadratic inequalities? I. 4x2 − 3x + 1 ≤ 0 II. (x + 9)(x − 7) > 0 III. 2 + 9 = 0
Write the equation x2 + 24x + 60 = 0 in the form (x + p)2 = q.
A. (x + 12)2 = –60
B. (x + 12)2 = 84
C. (x + 12)2 = 204
D. (x + 6)2 = –24
The Answer is
A.(x+12)2 = -60
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The formula for (a + b)² = a² + 2ab + b²
The equation x² + 24x + 60 = 0 in the form (x + p)² = q is
(x + 12)² = 84
Option A is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
x² + 24x + 60 = 0
We can write this as,
x² + 2 x 12 x (x) + 60 = 0
The formula for (a + b)² = a² + 2ab + b²
Add 144 on both sides.
x² + 2 x 12 x (x) + 60 + 144 = 0 + 144
x² + 2 x 12 x (x) + 144 + 60 = 144
[ 12² = 144 ]
Subtract 60 on both sides.
x² + 2 x 12 x (x) + 144 = 144 - 60
x² + 2 x 12 x (x) + 12² = 84
(x + 12)² = 84
Thus,
The equation x² + 24x + 60 = 0 in the form (x + p)² = q is
(x + 12)² = 84
Option A is the correct answer.

Suppose () = 46%; ( and ) = 10%; and ( or ) = 62% Find (Not ). Can this really be a probability? If not, explain why not.
Answer:
[tex]P(E) = 26 \%[/tex]
Step-by-step explanation:
Given
[tex]P(F) = 46\%[/tex]
[tex]P(E\ and\ F) = 10\%[/tex]
[tex]P(E\ or\ F) = 62\%[/tex]
Required
Find P(E)
In probability:
[tex]P(E\ and\ F) = P(E) + P(F) - p(E\ or\ F)[/tex]
Substitute the right values
[tex]10\% = P(E) + 46\% - 62\%[/tex]
[tex]10\% = P(E) -16 \%[/tex]
Collect Like Terms
[tex]P(E) = 10\% +16 \%[/tex]

Pippa owns a snack bar.
She uses
of a kilogram of spread each day.
Spread costs £3.20 for a 1 kilogram tub and £6.15 for a 2 kilogram tub.
Pippa buys enough spread to last for 14 days.
What is the lowest price Pippa can buy this spread for?
Answer:
£43.05 (I believe, refer to step-by-step explanation.)
Step-by-step explanation:
Let's compare both of these tubs if we were to buy either of them for 14 days.
Starting with the 1 kilogram tub we need to do the calculation:
£3.20 × 14 = £44.80
(Type 3.2×14 into your calculator or write on paper this way to calculate.)
Now let's do the 2 kilogram tub.
£6.15 × 7 = £43.05
(Type 6.15×7 into your calculator or write on paper this way to calculate.)
The reason why I have put 7 instead of 14 is because it is 2 kilograms. Since Pippa uses 1 kilogram per day, you only need to buy 7. 2 × 7 = 14
So comparing either of these prices, buying 7 2-kilogram tubs is much cheaper compared to the 14 1-kilogram tubs.
