PLS HELP DUE AT 11:59 AND I MISSED THE LESSON ON THIS

Answers

Answer 1

Answer:

try -14!

Step-by-step explanation:

4x+188=6x+216

x=-14

Answer 2

Answer:

x = -14

Step-by-step explanation:

To start since the angles are congruent then they must be equal to each other, so we start by setting them equal to each other. The equation will be 4x + 188 = 6x + 216

Next we solve for x, subtracting 188 and 6x from each side. The new equation will be

-2x = 28

Then divide both sides by negative 2 to get x = -14.

If A = 50 degrees, B = 62 degrees, and a = 4, find b.

Round to the nearest tenth.​

Answers

Answer:  4.6

=================================================

Work Shown:

Use the law of sines

b/sin(B) = a/sin(A)

b/sin(62) = 4/sin(50)

b = sin(62)*4/sin(50)

b = 4.61042489526572

b = 4.6

870 g of brass contains 40 percent zinic and the rest is copper.find the mass of zinic and copper in the alloy​

Answers

Step-by-step explanation:

Mass of Zinc = 870g * (40/100) = 348g.

Mass of Copper = 870g - 348g = 522g.

Mass of zinc = 40/100*870 = 348

Mass of Copper = 60/100*870 = 522

Therefore, the mass of zinic in the alloy is 348 and the mass of copper in the alloy is 522.

A grocery store sells tangerines in 25kg bags. A customer bought 4 kg of tangerines for a school party. How many bags did he buy? (2 points) A. Write a multiplication equation and division equation to represent the situation.

Answers

Answer:

x = 4/25

Step-by-step explanation

Amount of tangerines in bags sold = 25kg

If a customer bought 4kg of tangerines, the number of bags he bought is expressed as x;

4 kg = x bags

25 kg = 1 bag

Cross multiply

25 x = 4 * 1

25x = 4

Divide both sides by 25

25x/25 = 4/25

x = 4/25

Hence the required equation is x = 4/25

Answer:

So if you are in middle school like me, they are asking for an equation answer, and that equation is 4 divided by 2/5 = _ and _ x 2/5 = 4

To subtract in mathematics is to take something away from a group or a number of objects.

In other meaning, subtraction is a mathematical operation such that two values are going to subtract and give a resultant value.

As per the given,

The account balance initial = -$50

The amount of deposition = $75

Total amount = -$50 + $75

⇒ $25

the perimeter of a rectangle is (8x + 7y) feet, give two possible dimensions of the rectangle

please help ?? ​

Answers

Answer:

Two possible dimensions of the rectangle are 4x and 7/2 y.

Step-by-step explanation:

The Perimeter of a Rectangle

It's given the perimeter of a rectangle is

P = 8x + 7y

The formula to calculate the perimeter of a rectangle of dimensions L and W is:

P = 2W + 2L

Equating term by term, we can guess two possible dimensions of the rectangle:

2W = 8x

Dividing by 2:

W = 4x

And also:

2L = 7y

Dividing by 2:

L = 7/2 y

Thus, two possible dimensions of the rectangle are 4x and 7/2 y.

The family built a house that has a length and width in a ratio of 5: 4, what is the length and width of the house if the total area of ​​two identical floors is 160m2

Answers

Answer:

I hope it will help u , please Brain -list the question

Step-by-step explanation:

As given that

L:W=5:4

L/W=5/4

L=(5/4)W

hence we also know that

Area of rectangle= L*W

As given A=160m2

putt the value of A and L=(5/4)W in above equation ,

hence      160 = (5/4)W * W

W^2 = 160*4/5

W^2 = 32*4

W^2=128

taking square root  

W= +_ 11.3  

but length can't be negative so we take positive value of W  

W=11.3 m

Now for L putt in above equation,

L=5/4 * 11.3 = 14.12 m
