Answer:

7 (x-1)(x+5)

Step-by-step explanation:

Find

GCF = 7

Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

7 (7x^2/7 + 28x/7 - 35/7)

Simplify each term in parentheses.

7 (x^2 +4x-5)

Simplify.

Answer:

$7 {x}^{2} + 28x - 35 = 0$

$7 {x}^{2} + 35x - 7x - 35 = 0$

$7x(x + 5) - 7(x + 5) = 0$

$(x + 5)(7x - 7) = 0$

$(x + 5)(x - 1) = 0$

A survey asked students whether they would like a drama club, a step team, both clubs, or neither club. The results are below:

Hi, you've asked an incomplete question. Here are the remaining questions:

a) Describe what each region in the Venn diagram represents.

Region I: In drama club, not in step team.

Region II: In both clubs.

Region III: In step team not in drama.

Region IV: Not in either club.

b) How many students were in only one of the two clubs?

c) How many students were in the drama club or in the step team?

d) How many students were surveyed?

Attached is the Venn diagram depicting the regions.

Explanation:

b) By adding the number of students that like drama club and those that like step club we can derive the answer: 34 + 27 = 61.

c) By adding 34 + 27 + those that like both (14) = 75.

d) The total number of students surveyed is gotten by summing any number in attached the diagram: 34 + 27 + 14 + 13 = 88.

Sorry I need help with these 3! Thank you to whoever takes the time to solve them!!!

1.)
Starts with 40:10, then cuz you have 80 buns, you need to x2, so it would be 20 cubes

2.)
I don’t know, sorry

3.)
4:2 and 60 in total
so 4+2 is 6 and 60/6 is 10
so it would be 40:20 so 20

hope this helps :)

Hi can you help me with this problem i dont understand it

Romashka-Z-Leto [24]

Answer:

Answer is d - x = $\frac{y + z}{4}$

Step-by-step explanation:

Step 1: Add 'z' to both sides

4x -z (+z) = y + z

4x = y + z

Step 2: To solve for x, divide both sides by 4

$\frac{4x}{4}$ = $\frac{y + z}{4}$

x = $\frac{y + z}{4}$

Does anyone know the answer?

Alex787 [66]

Answer:

£0.60

Step-by-step explanation:

If each pack costs £1.59 and Nadia orders 15 packs,

then the total order before discount = 1.59 x 15 = £23.85

From the table given, we can see that for an order of £23.85 a 2.5% discount will be applied.

Divide £23.85 by 100 to get 1%: £23.85 ÷ 100 = £0.2385

Now multiply by 2.5 to get 2.5%: £0.2385 × 2.5 = £0.59625 = £0.60

Alternatively, the calculation in one expression is:

(1.59 × 15) × 0.025 = 0.59625
