Alex was thinking of a number. Alex doubles it, then adds 20 to get an answer of 22. 7. What was the original number?.

Answer:

D.-7

Step-by-step explanation:

Answer:

Step-by-step explanation:

If a = m + bt , find " m " when a = 24, b = 4 and t = 3

m=??

a = m + bt

24 = m + 4 * 3

24 = m + 12

m = 12

Answer:

m= 12

Step-by-step explanation:

If a = 24, b = 4, and t = 3,

24 = m + (4)(3) (Multiply 4 and 3 to get the value of bt)

24 = m + 12 (4 times 3 equals 12)

24 - 12 = m + 12 -12  (Subtract both sides to isolate the variable)

12 = m ( The answer is 12 since 24 minus 12 is 12)

The answer is 65 because bh/2=10*13/2=65

Step-by-step explanation:

you dont need to consider the volume. Just consider the area of cross-section area.

Answer:

y > 1/3x - 5

Step-by-step explanation:

First, use the points to find the slope.  Use the equation for slope.

Now, you need to find the y-intercept.  The y-intercept is the point on the graph that crosses the y-axis.  By looking at the graph, the y-intercept seems to be -5.

This gives you  1/3x - 5  for slope-intercept form.  

Now, you need to find which equality to use.  Because the line is dotted, it cannot be ≤ or ≥.  This leaves us with < and >.  To choose between the two, you need to test points.  Test a point to see if it matches the solution.  The point should be on the line but in the shaded area.

I'm gonna pick (0, 0).  This point is not on the line, and it is in the shaded region.

y   1/3x - 5

0   1/3(0) - 5

0   0 - 5

0 > -5

The equality > is the correct one.  This gives the equality  y > 1/3x - 5.

Answer:

sqrt(29)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

2^2 + 5^2 = ?^2

4+25 = ?^2

29 = ?^2

Taking the square root of each side

sqrt(29) = sqrt(/^2)

sqrt(29) = ?

Answer:

2 7/24

Step-by-step explanation:

2 2/5=12/5

Then multiply by the inverse: 11/2 times 5/12 which is 55/24

Then make 55/24 a mixed number 2 7/24

If it is 1 1/2 and not 11/2 then the answer is 3 3/5

Answer:

5/8

Step-by-step explanation:

Ii would convert them into 3/2 and 12/5

3/2 decided by 12/5 would how you would set up the equation, then you keep the 3/2 change the decision to multiplication, then flip 12/5 to 5/12 then you would do 3/2*5/12=15/24 which when you simplify you would get 5/8

Answer:

k=87

Step-by-step explanation:

Multiply k on both sides:

đổi 40ml = 0,04l

150ml = 0,15l

số nước mà silvia đã dùng là:

0,04 + 0,15 = 0,19 (l)

tổng số nước còn lại trong bình tưới là:

3,48 - 0,19 = 3,29 (l)

vậy tổng số nước còn lại trong bình tưới là 3,29 lít nước

The total amount of water remaining in the watering can of Silvia after watering the cactus and rose plant is 3.29 litres

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to decrease some item by 4 , then you can subtract 4 from that item to decrease it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

1 litre contains 1000 millilitres.

Given that:

3.48 litre = [tex]3.48 * 1000 = 3480[/tex] millilitres

Total water given to plants = 40+150 = 190 millilitres

Remaining water in water can = water it initially had - water given to plants = 3480 - 190 = 3290 millilitres

Converting this back to litre:

1000 millilitre = 1 litre

1 millilitre = 1/1000 litres = 0.001 litres

3290 millilitres =  [tex]3290 \times 0.001 = 3.29 \: \rm litres[/tex]

Thus, the total amount of water remaining in the watering can of Silvia after watering the cactus and rose plant is 3.29 litres

Answer:

5x-4y = -32

Step-by-step explanation:

We can first get an equation in point slope form since we have a point and a slope

y-y1 = m ( x-x1) where m is the slope and (x1,y1) is a point on the line

y- -2 = 5/4(x- - 8)

y+2 = 5/4 (x+8)

Multiply each side by 4 to get rid of fractions

4(y+2) = 5/4 *4 (x+8)

4(y+2) = 5(x+8)

Distribute

4y+8=5x+40

Subtracy 4y from each side

8 = 5x-4y+40

Subtract 40 from each side

8-40 = 5x-4y

-32 = 5x-4y

5x-4y = -32

Answer:

d=-8.9

Step-by-step explanation:

Isolate the d variable.

-9.39 - 3.4d = -1.1d + 11.08

-9.39 -2.3d= 11.08

-2.3d= 20.47

d=-8.9

Answer:

d = -8.9

Step-by-step explanation:

-9.39 - 3.4d = -1.1d + 11.08

-9.39 = 3.4d -1.1d + 11.08

-9.39 = 2.3d + 11.08

-9.39 - 11.08 = 2.3d

-20.47 = 2.3d

d = -20.47/2.3

d = -8.9

Answer: -3x

Step-by-step explanation:

combine the like terms and keep the operation that is not used which is the pulse sign.  

Answer:

-3x

Step-by-step explanation:

When adding with variables, combine like terms. Since all of the terms have the same variable and degree, they are all like terms. Additionally, there are parentheses. However, given that it is all added with like terms, they are unimportant. For the sake of PEMDAS, adding what is in the parentheses first might be easiest, but overall it does not matter.

Answer:

The slope is zero

Step-by-step explanation:

When the line is horizontal the slope will be zero and the line is vertical the slope will be undefined

Answer:

slope=0

Step-by-step explanation:

we can take any two point to denote that line, just like:-(0,-7) and (6,-7)

where,

(x1,y1)=(0,-7)

(x2,y2)=(6,-7)

we know that ,

slope=y2-y1/x2-x1

=-7 (-7)/6-0

=-7+7/6

Answer: y=4/1x-12

Step-by-step explanation:

i think sorry if this is wrong

The equation sin x = cos x can also be solved by dividing through by cos x. If we put k = 0 and k = 1 we get the solutions /4 (45°) and /4 + = 5 /4 (45°+ 180°= 225°). To solve the inequality sin x > cos x we need to see which is the greater sin x or cos x on the intervals between the solutions /4 and 5 /4.

hii! The answer is false. This is true because if you calculate the average of say, 2 and 4 will be 2+4=6. And we divide that by 2 and we get 3 as an answer. 3 Is NOT an even number.  I'm so bored that I'm chilling on brainly now smh. Anyways I hope u have a good night or day! - Castiel  (She/They)
