What is 4 to the third power plus 8 to the second power

Answer:

X = -2

Step-by-step explanation:

7x+6=5(X+2)

open the bracket

7x+6=5x+2

7x-5x=2-6

2x=-4

divide both sides by 2

X = -2

[tex] \huge \pink{solution}[/tex]

Given :7x+6=5(x+2)

Now We will use the distributive property to multiply 5 by x+2.

→7x+6=5x+10

We will Subtract 5x from both sides.

→7x+6−5x=10

We will Combine 7x and −5x to get 2x.

→2x+6=10

We will Subtract 6 from both sides.

2x=10−6

We will Subtract 6 from 10 to get 4.

2x=4

We will Divide both sides by 2.

x= 4/2

At last,We Divide 4 by 2 to get 2.

x=2

Answer:

3.15 for 9 apples

Step-by-step explanation:

2.45 divided by 7 is 0.35. 2.45+0.35=2.80 and thats 8. 9 is 3.15 because 2.80+0.35= 3.15. thats nine apples

Step-by-step explanation:

x - 4x - 12 = (x __ 2)(x ____ 6)

when they add negative

when they're multiplied negative

(x+2)(x-6)

because when u add them -6+2=-4

when u multiply them -6*2= -12

Answer:

y = 5/4 (x) + 7

Explanation:

Slope of a line (m): (y₂ - y₁) ÷ (x₂ - x₁)

       Slope: (2 - -3) ÷ (-4 - -8) = 5 ÷ 4 = 5/4

Point slope form: y - y₁ = m (x - x₁)

       Equation: y - 2 = 5/4 (x - -4)

                        distribute the 5/4

                        y - 2 = 5/4 (x) + 5

                        add 2 to both sides

                        y = 5/4 (x) + 7

I hope this helps!

1. 14 loaves are needed for 63 customers

2.  90 loaves

3. 4.5 loaf

Step by Step:

9/2= 4.5

4.5x4= 18

27/4.5=6

14x4.5=63

I multiplied and divided everything by 4.5 so one loaf of bread is 4.5.

(Correct me if I'm wrong)

I hope this helped! :)

Answer:

0° and 18°

Step-by-step explanation:

3tan²β - tanβ = 0

tanβ(3tanβ - 1) = 0

tan β = 0 ⇒ [tex]\beta _{1}[/tex] = 0°

3tan β - 1 = 0 ⇒ tan β = [tex]\frac{1}{3}[/tex] ⇒ [tex]\beta _{2}[/tex] = arctan ( [tex]\frac{1}{3}[/tex] ) ≈ 18°

Answer:

[tex]3 \tan {}^{2} \theta - \tan\theta= 0 \\ \tan\theta(3 \tan \theta- 1) = 0✓\\\\\tan\theta = 0 \\\boxed{\theta = 0°} ✓\\\\ 3 \tan\theta - 1 = 0 \\3 \tan \theta = 1 \\ \tan \theta = \frac{1}{3} \\ \theta = { \tan }^{ - 1} ( \frac{1}{3} ) \\\boxed{\theta = 18.4°}✓[/tex]

Answer:

ans -625

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) Number of jeans = x

Number of blouses = y

Total items = 6

x +  y = 6 -------------------(I)

       y = 6 - x

Cost of 'x' jeans =  300 *x = 300x

Cost of y blouses = 100 * y = 100y

Total amount  = Php. 1000

300x + 100y = 1000 ------------(II)

2) Substitute y = 6 - x in equation (II)

         300x + 100(6-x) = 1000

300x + 6*100 - x *100 = 1000

 300x + 600 - 100x   = 1000

                200x + 600=1000

                          200x = 1000 - 600

                          200x = 400

                               x = 400/200

x = 2

Plugin x = 2 in equation (I)

2 + y = 6

     y = 6 - 2

     y = 4

Number of jeans = 2

Number of blouses = 4

3) This equations have only one solution. So, they are consistent and independent

Answer:

yuki.ki

Step-by-step explanation:

The number of miles did he hike altogether is 4 miles.

Given that,

Based on the above information, the calculation is as follows:

= 2.5 miles + 1.5 miles

= 4 miles

Therefore we can conclude that the number of miles did he hike altogether is 4 miles.

Answer:

(0,5)

(2,1)

(4,-3)

Step-by-step explanation:

so all you have to do is plug in the x value and if the y value comes out to be whatever is matches up with then it is a solution to the equation for example if you plug in 0 to y=-2x+5 then you get 5 and below it says that when x=0 then y=5 which is true so that would be an answer now if you plug in 2 then you get 1 and it says that when x=2 y=9 which is not correct. sorry if this doesnt make sense its so hard to explain virtually

Answer:

No, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

Barbara buys 3 boxes of eggs costing £1.20 each

1 jar of mayo costing £1.80

2 loaves of bread

she pays £10 note and gets £1.60 change

Barbara works out the cost of 1 loaf of bread as £1.40.

Is she correct? You MUST show your working out.

The explanation of the answer is now given as follows:

Total cost of 3 boxes of eggs = Number of boxes of eggs bought * Price per box of egg = 3 * £1.2 = £3.60

Cost of 1 jar of mayo = £1.80

Total amount spent = Note paid - Change collected = £10 - £1.60 = £8.40

Total cost of 2 loaves of bread = Total amount spent - Total cost of 3 boxes of eggs - Cost of 1 jar of mayo = £8.40 - £3.60 - £1.80 = £3.00

Cost of 1 loaf of bread = Total cost of 2 loaves of bread / 2 = £3.00 / 2 = £1.50

Therefore, Barbra is wrong as cost of 1 loaf of bread is £1.50 not $1.40.

Answer:

i think its triangle

Step-by-step explanation:

im not  completly sure but i think the triagnle is the one cross secting the cube

Answer: Option B.

Step-by-step explanation:

By an online search, i found that the options are:

A: (123873, 24765, 25000, 5678)

B: (16287, 16728, 16827, 16872)

C: (98782, 98728, 98287, 98278)

D: (78082, 78802, 78208, 78028)​

The numbers will be arranged in increasing order if the difference between all the pairs of consecutive numbers in the set is positive (where the order of the numbers if from left to right):

For example, for the set A the differences are;

1) 24765 - 123873 = -99108

The difference is negative, then the second number is smaller than the first one, then the numbers are not arranged in increasing order.

Now let's see with set B:

1) 16728 - 16287 = 441

2) 16827 - 16728 = 99

3) 16872 - 16827 = 45

All the differences are positive, then the numbers on this set are arranged in increasing order.

We could easily see that in sets C and D the numbers are not arranged in increasing order, in set C the second number is smaller than the first one.

and in set D the third number is smaller than the second number.
