The sum of two numbers is 15 and the difference is 4. Let the two numbers be x and y.
Write down a pair of simultaneous equations involving x and y. Solve the equations.

Answer:

To solve for x, isolate it from the other terms.

Add 1 to both sides.

1/2x - 1 + 1 = 4 + 1

Combine like terms.

1/2x = 5

Multiply both sides 2.

x = 5(2)

x = 10

The solution is 10.

Hope this helps! :)

Explanation:

10h represents the cost of $10 per hour for h hours, where h is some positive whole number. We tack on the extra $5 to add on the cost of gas.

For example, if the babysitter works for 7 hours, then h = 7. It leads to a cost of 10h+5 = 10*7+5 = 70+5 = 75. The total cost is therefore $75 in this case.

Answer:

(x+x)+ (y+y)

=2x + 2y

Hey there!

x + x + y × y

= 1x + 1x + 1y × 1y

COMBINE the LIKE TERMS

= (1x + 1x) + (1y × 1y)

= 2x + y²

= y² + 2x

Therefore, your answer should be: y² + 2x

Good luck on your assignment and enjoy your day!

Hello! :)

A geometric sequence is a sequence where you use multiplication or division to get to the next term.

-4, -8, -16...

Here, we multiply every number by 2. So the common ratio is 2.

Hope it helps, and let me know if you have any queries.

Answer:

The answer is 2.

Step-by-step explanation:

To get the common ratio, simply dividing each number in the sequence from the number preceding it.

-4, -8, -16

-16 ÷ -8 = 2

- 8 ÷ -4 = 2

Answer:

the answer is 147

Step-by-step explanation:

first you do 3.5cm times 84cm which is 294cm

then you do 294cm divided by 2 which is 147cm

the reason why you divide by 2 is because parallelograms like the triangle can be also halved into 2 separate triangles!!

1:24/100

Step-by-step explanation:

you divide both side

Explanation:

Start at the point (3,4) which is the tail of the vector. We move 2 units to the right and 4 units up to arrive at (5,8) due to the vector a = <2,4>. Effectively, we're using the translation rule [tex](x,y) \to (x+2,y+4)[/tex]

In other words, we add 2 to the x coordinate and add 4 to the y coordinate of the point (3,4) to move to (5,8)

Answer:

15 pairs

Step-by-step explanation:

total:$20

cat food: $8:50

two pair of socks: $1.50

$20 - $8.50= $11.50(the rest of the money)

the rest is divided by the price of the socks to obtain how may socks you can pay with $11.50.

$11.50÷$1.50≈ 7.6

Now you multiply 7.6 by two to get the exact amount of socks with the offer.

7.6×2≈15.2

15.2≈15

So with $11.50 you will buy 14 socks for 1.50 every two pairs and a pair for 0.75

Answer:

were is the qn?

Step-by-step explanation:

Using the concept of place value, the digit 4 is 200 times greater than the digit 2.

Given the number :

The digit 2 is in the tens place = 2 × 10 = 20

The digit 4 is in the thousand place = 4 × 1000 = 4000

The number of times greater can be obtained thus :

Hence, the digit 4 is 200 times greater than the digit 2.

Answer:

-5x + 16

Step-by-step explanation:

I didn't see a equal sign so I assume that x cannot be x = -5/16

So I combined like terms of x and -6x to get -5x as well as +6 and +10 to get 16.

To get my final answer as -5x + 16.

Step-by-step explanation:

All trapezoids have a midsegment. The base angles of isosceles trapezoids are always congruent. Because the top and bottom side are parallel, the same side interior angles are supplementary not complementary.

Part 1. If x = -3 the equation would be. Y = -12-1 which would be Y= -13

Part 2. If x = -2 the equation Y = -8-1 which would be Y = -9

Part 3. If x = -1 the equation would be. Y =-4-1 which would be Y = -5

Step-by-step explanation: Identity the variable range .

Determine the scale of the graph.

Number and label each axis and title of the graph.

Show the positive and negative x-axis and y-axis

First , find the value of x on the x-axis . give x = 11 .

Find the value  of y on the y-axis . given y = 7.

Mark the point x=11 in the positive x - axis

Mark the point y=7 in the positive y - axis,.

After this meet the points by the help of scale and write the co-ordinates.

When you're asked to plot a point on a coordinate plane just remember that the coordinate given is of the form .

So, first, we need to plot 11 on the -axis (the line going left to right, horizontal) then plot 7 on the -axis (the vertical line)

So we first go 11 units to the right along the -axis then go up 7 units along the -axis.
