Can anyone find this answer?

Answer:

m=3

Step-by-step explanation:

add the m on the right side, 4m+3=15

subract the 3 on the left side, 4m=12

divide by four to isolate m, m=3

Answer:

[tex]3m+3=15-m[/tex]

[tex]3m+3=-m+15[/tex]

[tex]3m+m=15-3[/tex]

[tex]4m=12[/tex]

[tex]Divide\ both\ sides \ by\ 4[/tex]

[tex]\frac{4m}{4} =\frac{12}{4}[/tex]

Answer:

false

Step-by-step explanation:

because x - (-3)

= x+3

and x + - 3

= x - 3

so they are not the same

hope this helps

Answer:

False

Step-by-step explanation:

If u minus you go the opposite direction

And you have negative 3

So you do the opposite direction of -3 which is +3

So x+3

Answer:

(12,7) is not a solution

Step-by-step explanation:

Given

[tex]y\ge x+5\hspace{50px}y\ge\frac{2}{3}x + 6[/tex]

Required

Point that is not a solution

We have:

[tex]y\ge x+5\hspace{50px}y\ge\frac{2}{3}x + 6[/tex]

Substitute [tex]\frac{2}{3}x + 6[/tex] for y in the first inequality

[tex]\frac{2}{3}x + 6 \ge x + 5[/tex]

Collect like terms

[tex]\frac{2}{3}x - x \ge 5-6[/tex]

[tex]-\frac{1}{3}x \ge -1[/tex]

Solve for x (the inequality will change because we are to divide by a  negative number_

[tex]x \le -1/-\frac{1}{3}[/tex]

[tex]x \le 3[/tex]

Without solving further, we can conclude that the first option is not a solution.

Because (12,7) implies that [tex]x =12[/tex]

Compare [tex]x =12[/tex] to [tex]x \le 3[/tex], then [tex]x \le 3[/tex] is false

Answer:

Answer is the explanation!

Step-by-step explanation:

We know that x is the amount of seconds after the ball is dropped from the cliff and h is the height after that many x seconds.

So h(x) will represent the height of the ball after x seconds.

Meaning h(3) will reprensent the height after x seconds of being drooped.

We can simply replace x with 3 to find the height of it being dropped after 3 seconds.

Hoped this helped,

Answer:

Step-by-step explanation:

h(3) = -16(3)^2 + 200 = 56 (feet).  This is the height of the ball 3 seconds after having been dropped from a cliff, as measured upward from ground level.

"Every diameter of a circle is also a chord because a chord of a circle is any line segment joining two points on the circumference of the circle."

A diameter is a line that divides a circle into two halves, a diameter is also a chord

A chord is a line that connects points on a circle, a chord is not a diameter because it does not divide a circle into two equal halves

Answer:

88 square inches

Step-by-step explanation:

Surface Area =2(lw + lh + hw)

Length, l = 6 in

Width, w = 4 in

Height, h = 2 in

Surface Area = 2(lw + lh + hw)

= 2(6*4 + 6*2 + 2*4)

= 2(24 + 12 + 8)

= 2(44)

= 88 square inches

surface area of one box = 88 square inches

Answer:

Step-by-step explanation: The parallel sides of a trapezium are called the bases and the distance between them is the height. Therefore if 6cm and 15cm are the bases and 9cm is the height, then the area is A= ½(b1+b2)×h, where b1 is 6cm and b2 is 15cm and h is 9cm. Therefore the Area= ½(6+15)×9=94,5cm.

Answer:

x = 0.343

Step-by-step explanation:

We want to solve:

5 - 3tan(3x) = 0

such that:

-π< x < π

where π = 3.14

then:

-3.14 < x < 3.14

Let's solve the equation:

5 - 3tan(3x) = 0

-3tan(3x) = -5

tan(3x) = -5/-3 = 5/3

Now we can use the inverse tan function, Atan(x).

Remember that:

Atan( tan(x) ) = tan( Atan(x)) = x

Then if we apply that function to both sides, we get:

Atan( tan(3x)) = Atan(5/3)

3x = Atan(5/3)

x = Atan(5/3)/3 = 0.343

Answer:

173.2 cm²

Step-by-step explanation:

Use the equilateral triangle area formula, A = [tex]\frac{\sqrt{3}}{4}[/tex]a²

Plug in the side length and solve:

A = [tex]\frac{\sqrt{3}}{4}[/tex]a²

A = [tex]\frac{\sqrt{3}}{4}[/tex](20)²

A = [tex]\frac{\sqrt{3}}{4}[/tex](400)

A = 173.2

So, the area of the triangle is approximately 173.2 cm²

Given:

A metal is made from copper, zinc and lead in the ratio 13:6:1.

The mass of zinc is 90kg.

To find:

The mass of the metal.

Solution:

It is given that the metal is made from copper, zinc and lead in the ratio 13:6:1.

Let the mass of copper, zinc and lead are 13x, 6x and 1x respectively.

The mass of zinc is 90kg. So,

[tex]6x=90[/tex]

[tex]x=\dfrac{90}{6}[/tex]

[tex]x=15[/tex]

Now, total mass of the metal is:

[tex]Total=13x+6x+1x[/tex]

[tex]Total=20x[/tex]

[tex]Total=20(15)[/tex]

[tex]Total=300[/tex]

Therefore, the mass of the metal is 300kg.
