Answer:

17.5

plsss mark brainliestt

Step-by-step explanation:

10÷4=2.5

7×2.5=17.5

Answer:

4/7=10/x

or, 4×x=10×7

or, 4x=70

or, x = 70/4

or, x = 17.5

Thus, x is 17.5

Answer:

y ≥ -2x + 2.5

Step-by-step explanation:

It's kind of hard to tell because no points are given on the graph, but we can first find the b value of 2.5 in the equation y = mx +b  as it is the y-intercept.

Using that value, we can also recognize that at one, it looks like the y-value is .5. using our slope formula (change in y / change in x), we can plug in the two points of (0, 2.5) and (1, 0.5) to get a slope of -2.

Now that we have our equation, we can make it an inequality!  

Since the graph is shaded upwards, we know it is going to be a greater than symbol, and since the line itself solid and not dotted, we know that the points on the line are also solutions, meaning that it is also equal to the line

Hence, we get the ≥ sign.

Putting it all together, we get our final equation of y ≥ -2x + 2.5 ! :))

Answer:

x × x +2x-35=0

x²+2x-35=0

(x+7)(x – 5)=0

x+7=0 —> x= – 7

x – 5=0 —> x = 5

Answer:

720 minutes

Step-by-step explanation:

Total phone bill = $127.95

Service plan fee = $19.95

Total cost per minute = 127.95 - 19.95

= $108.00

No. of minutes used = Total cost per minute / Rate per minute

= 108.00 / 0.15

= 720 minutes

Answer:

None of the pairs of expressions are equal

Step-by-step explanation:

• 2n ≠ 2 +n

2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.

•n² ≠ 2n

n²= n ×n

2n= 2 ×n

• 2n² ≠ (2n)²

Note that in the latter, there is a bracket which means that the square applies to both 2 and n.

(2n)²

= (2)² × n²

= (2 ×2)(n²)

= 4n²

Thus, none of the pairs of expressions are equal.

Answer:

Step-by-step explanation:

Neither.

It is a complex number. The - sign is the culprit. sqrt(-144) = i * sqrt(144) = 12 i

The "i" is an imaginary representation for the square root of -1. It is a definition for sqrt(-1). So a new category of number has been created. The ancients would have been profoundly surprised to learn that such a thing existed.

Answer:

-120

Step-by-step explanation:

(5)8x

(5)(8)(-3)

5(-24)

= -120

Hi! I'm happy to help!

To solve this, we just have to insert -3 for x. Because the 5 in parenthesis is next to the eight with no other sign, it represents multiplication. Since the eight is next to the x with no other sign, it also means multiplication.

(5)8x

(5)·8·x

We can remove the parenthesis.

5·8·x

5·8·-3

40·-3

-120

So, when x=-3, (5)8x evaluates to -120.

I hope this was helpful, keep learning! :D

Explanation:

I'm assuming you meant to say the area is 375 in^2, aka 375 square inches.

If so, then,

area of rectangle = length*width

A = L*W

A/L = W

W = A/L

W = 375/25

W = 15 inches

As a check,

A = L*W = 25*15 = 375 which helps confirm the answer.

Answer:

No, they are co-planar.

Step-by-step explanation:

Points Q, R, X, and W are all in the plane QRXW. Planes do not have to be at ninety-degree angles (that is, straight up and down or straight to the left and right). However, the points Q, S, U, and X would not be coplanar as a plane must be a flat surface.

Each group used 9 pictures, first divide total pictures by pictures per group to find total groups:

585 / 9 = 65 total groups.

Each group had 3 students.

Multiply total groups by students per group:

65 x 3 = 195 total students

Answer: 195 students.

The fraction of money spent is 5 / 8 x.

The fraction of money left is 3 / 8 x.

This week Harry spent 1/2 of his pocket money on a ticket for a football match. Therefore,

let

x = amount of money he has

Therefore,

amount spent on football match = 1  /2 x

He also spent 1/8 of his pocket money on a scarf at the match.

Therefore,

amount spent on scarf = 1 / 8 x

Fraction of money spent = 1 / 2 x + 1 / 8 x = 4 + 1 / 8 = 5 / 8 x

Fraction of money left = x - 5/8 x = 8x - 5x/8 = 3 / 8 x
