Liz purchased three trays of tomato plants for $16.47. She also bought ten trays of basil plants. If the ratio of the price per tray of tomato plants to the price per tray of basil plants is 3 to 2, then how much did she spend in total for all the plants? Write and solve a proportion.

Please help! Tysm <3

Answers

Answer 1

Step-by-step explanation:

Start by creating expressions

t= A tray of tomato plants

3t = $16.47

Solve the equation above

3t/3= 16.47/3

t= 5.49

A tray of tomato plants costs $5.47

Now create the ratios

b= A tray of basil plants

t:b = 3:2

Substitute t

5.49:b = 3:2

Rewrite as fractions

[tex]\frac{5.49}{b}[/tex] = [tex]\frac{3}{2}[/tex]

Cross multiply

5.49(2) = 3(b)

10.98 = 3b

10.98/3 = 3b/3

3.66 = b

A tray of basil plants costs $3.66

In total she bought 3 trays of tomato plants, which cost $16.47, and 10 trays of basil plants

T0 find out the cost of the 10 basil plants, multiply 3.66 by 10

3.66 × 10 = 36.6

She bought 10 trays of basil plants for $36.60 and 3 trays of tomato plants for $16.47

Add the 2 values together

36.60+16.47 = 53.07

$53.07 is the total

I hope this helps!!!

Answers

Answer:

y = -4x - 9

Step-by-step explanation:

First, I plotted the dots (0, -9) and (-1, -5). I then drew a line connecting these two points. Since -9 touches the y-axis that is the y-intercept. Starting at the point (-1, -5), I went down four and one square to the right. This means that my slope is -4, thus the equation y = -4x - 9

y = -4x - 9

Help fast Please!!!!! What is the vertical distance between
(-3, -2.5) and (-3, 5)?

Answers

What I can tell is that they both share the same x coordinate. To help you understand, the horizontal line is from left to right, think of "The sun setting in the horizon.", it is often in the distance as a "left to right" line. So, I hope that helps, this leaves the vertical line as up or down.

With that out of the way, the x-axis lies on the horizontal line, whereas the y-axis lies on the vertical line.

Point coordinates are typically listed as (x, y), so... with that said, to find the distance we'll have to count downwards. As we know, negative x is to the left, negative y is further down, so... -3 to -12 is 9 points away.

Simple method: -3 - 9 = -12, or... -12 - -3 = -12 + 3 = -9.
In other words you get the basic idea, you can also just count, but whatever.

I hope that helps, have a great rest of your day! ^ ^
