The two shorter sides of a triangle are the same length. the length of the longer side is 5 m longer than each of the shorter si

ziro4ka [17]

P=a+b+c. Sub in what we know: 29=a+a+(a+5). Combine like terms: 29=3a+5. Subtract 5 from both sides: 24=3a. Divide by 3: 8=a. Short sides: A=8m, b=8m, long side: c=13m. :)

Jessica is baking a cake. The recipe says that she has to mix 96 grams of sugar into the flour. Jessica knows that 1 cup of this

Rudik [331]

1 cup = 128 grams
X cups = 96 grams

Cross multiply
128X = 1*96
X=96/128 cups = 6/8 = 3/4 cups.

If she has already added 1/2 cups, then she needs to add (3/4-1/2)=1/4 cup more sugar.

Also please remind her to do the calculations before adding ingredients to avoid ruining a recipe.

The area of a parallelogram is 60 feet the height 5 feet how long is the base

Kobotan [32]

Hello!

We have to use a certain formula to find the area of a parallelogram. The formula is:

A = bh

Since we already have the area and the base of the parallelogram, we will be able to find the height!

Notice how we multiply the base by the height to find the area? Well, we'll have to do the opposite to find one of its dimensions.

What's the opposite of multiplication? Division!

Formula for base:

B = A ÷ h

Substitute:

B = 60 ÷ 5

B = 12

ANSWER:

The base is 12 feet long.

Good Day!

BRAINLIEST TO WHOEVER IS CORRECT!!!

Answer:

y= $-\frac{4}{3}$ x+2

Step-by-step explanation:

To write the equation for this line, we are going to use slope-intercept form, which is written as

y=mx+b.

Here are the meanings of each variable:

y= basically the "name" of the function and it always stays as y.

m= slope, which is rise over run.

x= variable that is always on the right of the slope and it always stays as x.

b= y-intercept, or the value that crosses the y-axis.

We will substitute numbers into the equation along the way. The first thing we will want to do is find b, which is the easiest.

The line crosses the y-axis at 2, so that is our value of b.

Our new equation is

y=mx+2.

Next, we will find the slope. The most efficient way of doing this is looking at the lowest point that is already provided, (3, -2), and finding a way to rise and run to the highest point, (0, 2).

If you look closely at the graph, we need to rise up 4 and run over -3 to get to the other point. Therefore, the slope is $-\frac{4}{3}$ , and we can substitute it into our equation, which is completed and is now

y= $-\frac{4}{3}$ x+2

I hope this helps you out!! Have an awesome day ^^
