Answer: The answer is 20x + 35

Step-by-step explanation: 5(4x+7) You multiply 5 in both numbers and you get 20x+35

Answer: 20x+35

Step-by-step explanation:

Multiply both terms in the parenthesis by 5. 4x times 5 is equal to 20x, and 7 times 5 is equal to 35.

Answer:

52 when we evaluate it understand

Answer:

5-2x=4-2x+4+x=8-x

x=5-8=-3

Answer:

The answer is B. One solution.

CF is 7

Step-by-step explanation:

GE is 10 and they have to be equal so 10-3 is 7

Answer:

a. root (x^2 + 64)

Step-by-step explanation:

(8^2 + x^2) = y^2

If you root both sides,

y = root (x^2 + 64)

Answer:

10x I think

cause X divide by 6 is X/6

then X/6 x 60min(1h) is 60x/6 which is 10x

hope this helps:))

Answer: 16-p=C

p is price of the wallet and it has to be either less than or equal to the 16 dollars spending money. And that result will equal C which represent the change or what's left after spending unknown amount from 16

Answer:

2

Step-by-step explanation:

first step: simplify the problem to get 5

Second step: 7-5=2

Answer:

y=+|x-3|

Step-by-step explanation:

We know it is positive because it is expanding upward. So +. We know it is x-3 because if it is inside the absolute value signs, the constant(-3 in this case) is opposite. So it is 3. And 3 matches with the vertex of the graph. And the ending is 0, so I omitted it bc its still on the x intercept, meaning it has a y value of 0.

Answer:

fam good luck

Step-by-step explanation:

Answer:

Step-by-step explanation:

ΔH + ΔJ + ΔK + ΔG = 360°

103° + 133° + 58° + X = 360°

294° + X = 360°

X = 360° - 294°

X = 66°

Answer:

It a vertical line x=3.

Answer:

6 the answer is 6

Step-by-step explanation:

-3 -2 -1 0 1 2 3 4 5 6

[tex] \bf \: Appropriate \; question :-[/tex]

[tex] : \implies 4 = - 2 + \boxed{ {?} }[/tex]

[tex] \bf \huge \: Solution :-[/tex]

[tex] \rm \: Let \: us \: assume \: that \: the\: value\: of \: \boxed{} \: be\: \bf \: x.[/tex]

New Equation will be :

[tex] : \implies \sf \: 4 = - 2 + \bf x[/tex]

[tex] \rm \: This \: equation \: may \: be \: rewritten \: as :- [/tex]

[tex]: \implies \sf \: 4 = x - 2[/tex]

[tex]\underline{ \rm \: Flip \: this \: equation :-}[/tex]

[tex]: \implies \sf \: x - 2 = 4[/tex]

[tex]\underline{ \rm \: Add \: 2 \: t o \: both \: sides:-}[/tex]

[tex]: \implies \sf \: x - 2 + 2 = 4 + 2[/tex]

On Simplification of this equation,

[tex]: \implies \sf \: x - 0 = 6[/tex]

[tex]: \implies \sf \: x = 6[/tex]

[tex] \underline{ \rm Put \: 6 \: instead \: of \: x \: on \: this \: e quation :-}[/tex]

[tex]: \implies \tt \: 4 = - 2 + \boxed{}[/tex]

[tex]\boxed{\boxed{\bf4 = - 2 + \boxed{\bf 6}}}[/tex]

Hence, the missing value is 6.

Answer:

5 days

Step-by-step explanation:

60 ÷ 12 = x

x represents the amount of days

the elephant get 12 lbs. per day

60 is the total amount of lbs.

Answer: 5 days

Step-by-step explanation:

Okay, so we use the equation 12x=60. She gives the elephant 12 peanuts a day but we don't know how many days so we put x.

Now to solve this, we must divided 12 on both sides and get 5.

12x=60

÷12 ÷12

x=5

Answer:

Step-by-step explanation:

The discriminant of ax^2+bx+c=0 is b^2-4ac, in this case

4^2-4(2)10

16-80

-64

Since -64<0 there are two imaginary (or ‘complex’) solutions.

Note: if d=0, there is one real solution. if d>0, there are two real solutions.

Answer: Each girl gets 7/8 or 0.875 of the sandwich .  

Step-by-step explanation:

Number of sandwiches = 7

Number of people to share = 8

Therefore  Each girl gets =  7 ÷ 8= 7/ 8

Each girl gets 7/8 or 0.875 of the sandwich .

Answer:

A

Step-by-step explanation:

Given the graph of f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift to the left of a units

• If a < 0 then a shift to the right of a units

g(x) is the graph of f(x) shifted 1 unit to the left , then

g(x) = (x + 1)² → A

Answer:

[tex]1\%[/tex]

Step-by-step explanation:

Simple interest (I) = $160

Principal amount (P) = $2000

Time period (t) = 8 months

Let R denotes rate of interest.

Relation between simple interest, principal amount, time and rate of interest  is given by [tex]I=\frac{PRT}{100}[/tex]

[tex]160=\frac{2000(R)(8)}{100} \\\\160=160R\\R=1\%[/tex]

Answer:

12

Step-by-step explanation:

It would be: r = I * 100 / P * R

r = 160.67 * 100 / 2000 * 2/3

r = 16067*3 / 4000

r = 48201 / 4000

r = 12

Answer:

4.0

Step-by-step explanation:

Given that

3.9931

Now rounded to one decimal places

3.9931 = 4.0

So the above value would be rounded to one decimal places after rounded off it comes 4.0

Answer:

40 feet

Step-by-step explanation:

Answer:

40 feet tall

Step-by-step explanation:

6/2 =3

?/2 =20

*2    *2

? = 40

you do inverse operations because 6 divided by 2 is 3... the ? is the variable for how tall the building is... ? divided by 2 = 20 so you multiply 2 and 20 to get the total height
