Three times a number, x, increased by four is equal to five times the number, x. Which equation can be used to solve for x?a.3x+5x=4
b.3x+4=5x
c.3x=4+5x
d.3x-4=5x

Answers

Answer 1
Answer:

Answer:

The value of x is 2 .

Option (b) is correct .

Step-by-step explanation:

As given

Three times a number, x, increased by four is equal to five times the number, x.

Thus the equation becomes

3x + 4 = 5x

5x - 3x = 4

2x = 4

x = (4)/(2)

x = 2

Therefore the value of x is 2 .

Option (b) is correct .
Answer 2
Answer: its B cause 3times a number x increased by 4 is equal to five the number x.3x+4=5x

The surface area of a triangular pyramid is 375.2 m2. What would change if the surface area were measured in square centimeters?   A. The surface area of the pyramid would decrease.   B. The surface area of the pyramid would increase.   C. The surface area of the pyramid would stay the same, but the number representing the surface area would decrease.   D. The surface area of the pyramid would stay the same, but the number representing the surface area would increase

Answers

D. If I told you to walk 1 metre or 100cm you would have walked the same distance but more cm as the ratio of cm:m is 100:1, this is the same thing for surface area except the ratio is 1000:1

I need help to graphs these problem please

Answers

If you're talking about #5, where you have to graph the equation . . .

All you have to do is find two points on the graph, and draw a line between them.

How do you find points ?  That's where you are in control !
Just pick any number you like for 'x', and then use the equation
to calculate the 'y' that goes with it.

Examples:

Pick 'zero' for 'x'. 
Y = (1/2)x + 3
Y = 3

Pick 10 for 'x'.
y = (1/2)x + 3
y = 5 + 3
y = 8

Just create two points that way, using the equation.  Then mark
the two points on the graph, and draw a line through the two points.

What's the hypothesis of a triangle ?

Answers

The hypotenuse of a right-angled triangle is the square root of the sum of squares of perpendicular and base,   h=√(b^2+p^2)

A triangle is a figure consist of 3 sides. A triangle is only formed when the sum of  two sides is greater than the third side.  A right-angled triangle is a triangle in which one angle is of 90 degrees.

Here, for hypotenuse to exists, the required triangle must be a right-angled triangle. Three sides of the right-angled triangle are Base, perpendicular and Hypotenuse.

Let,

Base of the right-angled triangle = b

Height of the right-angled triangle = p

Hypotenuse of the right-angled triangle = h

where h²=b²+p²

h=√(b^2+p^2)

So, hypotenuse is the square root of the sum of squares of perpendicular and base.

Correct question:

What is the hypotenuse of a right-angled triangle?
It is the slant side of the triangle its the longest side or in other words it forms a 90 degree angle the side thats going from top to bottom is you hypotenuse

The Smiths are sending out a batch of holiday cards. Emily signed 2/5 of the cards. Then Josh signed 1/9 of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed? There are____ cards yet to be signed.

Answers

There are 32 cards left

Answer:

32

Step-by-step explanation:

start with 75 cards.  Emily did 2/5 of the 75 cards = 30 cards (75 divided by 5 times 2)

75-30=45 cards

Josh signed 1/9 which you have to convert to irregular fraction (45 divided by 9 =5) so 45-5=40 left

Of those left Tatiana completed 20% (40*.20=8)

so 40-8=32
