7x-8<4x+7 solve for x

Answer:

it would be 5

Step-by-step explanation:

I don't have an explanation I just know it is 5

Answer:

A.) 65x + 35X + 50 = 250

65x = cost of concrete per cubic yard, x is yd³

35X = cost of pouring/finishing concrete per cubic yard, X is yd³

50 = delivery cost

250 = the money you have

B.) 400 + 15n = 505

15n = amount of money you deposite per week, n is # of week

400 = some money in account after n week passed

505 = initial money in bank

C.) 1.1X - 10 = 55

55 = total cost of clothes

1.1X = tax rate where X is the undiscounted clothe cost

10 = discount

Answer:

C=550 pounds

Step-by-step explanation:

Given the formula: C=p(t+30)

and with p=2 and t=245 known.

We can plug our values of p and t into our formula. Once we do this, the only unsolved variable will be C.

C=2(245+30)

Add 245+30 first because they are in parentheses and we must abide by the order of operations.

C=2(275)

Now we just multiply 2(275) because this is all that's left in the formula.

C= 2*275 = 550

We now know that C=550 when p=2 and t=245, but we need to apply units to finalize the answer. We are told that C represents the total cost in "POUNDS", so pounds is our units for variable C.

Our final answer is...

C=550 pounds

x is greater than -5

Answer:

1 lb=2 batches     3/4 lb=1 1/2 batches     1/4 lb= 1/2 a batche

Step-by-step explanation:

1x2=2   b

3/4x2=1   1/2   b

1/4x2=1/2   b

b=batches

Answer:

EF = 7

Step-by-step explanation:

the two triangles shown are congruent triangles

we know this because they share the line FD

and DE and DG are both 5

so the length two sides are definitely congruent, this means that the third side will also be congruent

the third side would be FG and EF

FG is 7 so then EF is 7

Answer:

EF is 7                

Step-by-step explanation:

Key skills needed: Triangle Congruence

1) We need to find out The length of EF

2) To find this, let's use Congruence of Two Triangles

The triangles that we can prove congruent are Δ DFG and Δ DFE

3) Both share the side DF, so we have one side

Both have a right angle, < FDG is a right angle, and < FDE would also be right angle (you can prove this as ---> < FDE is supplementary to a right angle, and therefore it would also be a right angle)

Both share a congruent set of sides (GD and DE both are 5)

4) With the 3 things above we can say -->  Δ DFG ≅ Δ DFE with SAS (side-angle-side)

5) This means that corresponding parts would be congruent.

FG ≅ EF. This means EF would be the same length as FG. Since FG is 7, then EF would be 7.

Hope you understood and have a nice day!! :D

Answer:

divide 88 by the number of x

88/8= 11

X = 11

Answer:

x=11

Step-by-step explanation:

8x=88

You use inverse operation which means you would divide 8 on both sides to isolate x on one side resulting in x=11

Step-by-step explanation:

I' sorry if it isn't right I tried my best.

Answer:

B

Step-by-step explanation:

This is due to the fact that the first equation is saying it is equal to y so you replace the y variable with the equation

Answer:

since y=2x+4 just substitute y with 2x+4

2x + 3(2x+4) = 8

so the answer is B

Answer:

c

Step-by-step explanation:

I I don't even know why it seems I just chose that because

The distance between (4, 3) and (9, 15) on the coordinate plane is 13 units.

The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.

The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁)².

We have to determine the distance between (4, 3) and (9, 15) on the coordinate plane.

As per the question, the required distance would be as:

distance = √ (9 – 4)² + (15 – 3)²

distance = √ (5)² + (12)²

distance = √ (25 + 144)

distance = √ 169

distance = 13 units

Given:

[tex]\Delta ABC\sim \Delta D E F[/tex]

[tex]AB=18,BC=21,AC=24,EF=7[/tex]

To find:

The scale factor of [tex]\Delta ABC[/tex] to [tex]\Delta D EF[/tex].

Solution:

We have,

[tex]\Delta ABC\sim \Delta D EF[/tex]

So, side BC is the corresponding side of EF.

Now, scale factor of [tex]\Delta ABC[/tex] to [tex]\Delta D EF[/tex] is

[tex]\text{Scale factor}=\dfrac{\text{ Side of }\Delta D EF}{\text{Corresponding side of }\Delta ABC}[/tex]

[tex]\text{Scale factor}=\dfrac{EF}{BC}[/tex]

[tex]\text{Scale factor}=\dfrac{7}{21}[/tex]

[tex]\text{Scale factor}=\dfrac{1}{3}[/tex]

Therefore, the scale factor of [tex]\Delta ABC[/tex] to [tex]\Delta D EF[/tex] is [tex]\dfrac{1}{3}[/tex].  

Answer:

270 degrees.

Step-by-step explanation:

A full rotation is equal to 360 degrees. 3/4 * 360 = 270.

Answer:

x=15

Step-by-step explanation:

Add the two equations together because there is a 90 degree angle. You can add the two to get :

4x+30=90

-30 from both sides

4x=60

Divide by 4 on both sides to get your answer!

x=15

Answer: X = 15

Answer:

$5.67, or $6 rounded to the nearest dollar.

Step-by-step explanation:

To determine the amount that both Ian and Addison will have in their respective accounts after 13 years, knowing that they both invested $ 100 in accounts with daily compound interest, but Ian did it in one with an interest of 9.25% while Addison did it in one with a interest of 9.375%, the following calculations must be made:

Ian = 100 x (1 + 0.00925 / 365) ^ 13x365

Ian = 332.79

Addison = 100 x (1 + 0.009375 / 365) ^ 13x365

Addison = 338.46

338.46 - 332.79 = 5.67

Therefore, Addison will have $ 5.67 more than Ian after the investment term.
