Answer:

required equation,3x+y=-11

Step-by-step explanation:

given slope=-3, line passing through point (-2,-5)

equation of line, ${y-y_1}$ = $m[{x-x_1]}$

where m= slope of line

equation of line,y+5=-3(x+2)=-3x-6

equation of line,3x+y=-11

Whats the answer too this 2(3+2×5)÷2?<br>

icang [17]

Answer:

Step-by-step explanation:

Use PEMDAS

2(3+2x5)÷2

first you would do the parenthesis

2 times 5 is 10

so now you have:

2(3+10)÷2You still have parenthesis so you would add 3+10 because that is inside the parenthesis

2(13)÷3

next you would do 2 times 13 which is 26:

so now you have 26÷2 which is 13

so the answer is 13

A train traveling nonstop to its destination is able to make the trip at an average speed of 70 miles per hour. On the return tr

larisa86 [58]

Answer:

Return trip travel time: 7h

Step-by-step explanation:

Let d be the distance.

Index 1 refers to initial trip, index 2 refers to the return trip.

v1=70mi/h

v2=40mi/h

t2=t1+3h, or t1=t2-3h (travel times)

d=v1×t1=v2×t2

v1×(t2-3)=v2×t2

v1 t2 -3 v1=v2 t2

v1 t2 - v2 t2=3 v1

t2(v1-v2)=3v1

t2=3v1/(v1-v2)

t2=3×70/(70-40)=3×70/30=7h

Alexeev081 [22]

Answer:

There are 23 cats for every 36 dogs at the city pound

92 to 144 or 92/144 = 23/26 or 23 to 36

A hair care company makes three batches of scented shampoo using the recipe shown. Each batch contains a different total amount

mr_godi [17]

Answer:

Batch 1: Pineapple = 3 1/2; Banana = 1 2/5

Batch 2: Pineapple = 8; Coconut = 4 4/5

Batch 3: Banana = 1; Coconut = 1 1/2

Step-by-step explanation:

For Batch 1:

We know that coconut is 3/10 of the mixture, and we have 2 1/10 coconut:

3/10x = 2 1/10

Converting 2 1/10 to an improper fraction, we have

3/10x = 21/10

Divide both sides by 3/10:

3/10x ÷ 3/10 = 21/10 ÷ 3/10

To divide fractions, flip the second one and multiply:

x = 21/10 × 10/3 = 210/30 = 7

This means we have 7 total of the mixture.

1/2 of this is pineapple: 1/2(7) = 7/2 = 3 1/2

1/5 is banana: 1/5(7) = 7/5 = 1 2/5

For Batch 2:

1/5 of the total is banana; we have 3 1/5 banana:

1/5x = 3 1/5

Convert the second fraction to an improper fraction:

1/5x = 16/5

Divide both sides by 1/5:

1/5x÷1/5 = 16/5÷1/5

Flip the second fraction and multiply:

x = 16/5×5/1 = 80/5 = 16

We have 16 of the total shampoo.

Pineapple is 1/2 of this:

1/2(16) = 8

Coconut is 3/10 of the total:

3/10(16) = 48/10 = 4 8/10 = 4 4/5

For Batch 3:

Pineapple is 1/2 of the total. We have 2 1/2 pineapple:

1/2x = 2 1/2

Convert the fraction on the right to improper:

1/2x = 5/2

Divide both sides by 1/2:

1/2x÷1/2 = 5/2÷1/2

Flip the second fraction and multiply:

x = 5/2×2/1 = 10/2 = 5

We have 5 total shampoo.

Banana is 1/5 of this:

1/5(5) = 1

Coconut is 3/10 of this:

3/10(5) = 15/10 = 1 5/10 = 1 1/2
