4х – у = 5
3х + y = 9

Answer:

6

Step-by-step explanation:

Answer:

Step-by-step explanation:

(a) Since values 5 or up go up and 4.9 and under go down, Naomi could have gone 4555 to 4564.9, as 4555 rounds up to 4560 (and is the largest number that does so) and vice versa for 4564.9

Similarly, Peta could have went from 4550 to  4649.9.

(b)

Peta could have walked 4550 and Naomi 4564.9, so this could be true

Peta could have walked 4649.9 and Naomi 4555, so this could be true

Peta could have walked 4555 and Naomi 4555, so this could be true.

All values here are in the ranges of (a)

(a)

155 to 124.9

1.235 to 1.244

0.01235 to 0.01244

Answer:

−15w+25z

Step-by-step explanation:

Let's simplify step-by-step.

−5w−5(−4z+2w)+5z

Distribute:

=−5w+(−5)(−4z)+(−5)(2w)+5z

=−5w+20z+−10w+5z

Combine Like Terms:

=−5w+20z+−10w+5z

=(−5w+−10w)+(20z+5z)

=−15w+25z

Answer:

-15w + 25z

Answer:

15miles//hr

Step-by-step explanation:

From the question, we are given;

Distance covered by Paola = 3/5 miles

Time = 1/25 of an hour

Speed = Distance/ time

Substitute

Speed = (3/5)/(1/25)

Speed = 3/5 * 25/1

Speed = 3 * 5

Speed = 15

Hence Paola's running speed in miles per hour is 15miles/hr

Answer: 0.514

Step-by-step explanation:

Answer:

The answer is B choice.

Explanation:

Compare two graphs, the transformation of the graph is g(x) while f(x) is an original.

[tex]f(x) = 6x \\ g(x) = 6x -5[/tex]

For a linear function or line graph.

[tex]y = mx + b[/tex]

This means that the function y has the graph that shifts up b units.

[tex]y = mx - b[/tex]

While on the other hands, if the function y has -b as y-intercept. We can say that the function has the graph that shifts down b units.

Rather say that. If the constant term is positive, it shifts up and if the constant term is negative, it shifts down.

Back to the answer.

Comparing two graphs, from f(x) and g(x) —

We can say that function g shifts down 5 units from f(x) ^ Read the topic above before this ^

Thus, the answer is B.

Answer: is 28.8 miles per gallon

Step-by-step explanation:

Given:

Circumference of a circle = C

Diameter of a circle = d

To find:

The relationship between the circumference, c, and diameter, d, of any circle.

Solution:

We know that, circumference of a circle is

[tex]C=2\pi r[/tex]

It can be written as

[tex]C=(2r)\pi [/tex]

[tex]C=d\pi [/tex]         [tex][\because d=2r][/tex]

On dividing both sides by d, we get

[tex]\dfrac{C}{d}=\pi [/tex]

Therefore, the correct option is (F).

Answer:

for members: 1, 2,3,4,5

for non-members : 2,4,6,8,10

will cost same.

Step-by-step explanation:

6 + 2 = 8

members total $8 for 1 class

non-members total $4 for 1 class

8×2=16

8×3=24

8×4=32

8×5=40

4 × 2 = 8

4×3=12

4×4=16

4×5=20

4×6=24

4×7=28

4×8=32

4×9=36

Answer:

8x9=72 (9)+9+9=27

Step-by-step explanation:

am I right?

Answer:

The missing number is 54

Step-by-step explanation:

72 = __ + 18

72 - 18 = x

54 = x

8 x 9 = 54 + 9 + 9

72 = 72

Answer:

Step-by-step explanation:

(5d^4 - 8)^2

This is a perfect square.

Note an exponent multiplied by an exponent is the addition of them so

d^4 X d^4 = d^8

or

(d^4)(d^4)=d^8
