3x - 10 = x + 4 <== ur equation
three times a number.....3x...with the x representing the number
ten less....3x - 10
is the same as...means =
that number (x) increased by 4....x + 4
so we have 3x - 10 = x + 4...
3x - 10 = x + 4
3x - x = 4 + 10
2x = 14
x = 14/2
x = 7....and that number is 7
Answer:
x=2
Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2
Answer:
Obtuse angles have a measure that is greater than 90 but less than 180 degrees, while acute angles have a measure that is less than 90 but greater than 0.
Step-by-step explanation:
Obtuse angles have a measure that is greater than 90 but less than 180 degrees because 180 degree angle is a straight angle. Any angle that is greater than 181 but less than 360 degrees is known as a reflex angle. Acute angles have a measure that is less than 90 but greater than 0 because anything with a higher of lower degree of measure would be consider a different angle.

h(2.5)
- -16(2.5)²+58(2.5)+2
- -16(6.25)+145+2
- 147-100
- 47ft
After 2.5s the ball was at 47ft

Answer:
40
Step-by-step explanation:
<h2><u>Ratios </u></h2>
16 is to 10 as what number is to 25
this makes use of ratios
16 : 10
x : 25
hence we can make use of cross multiplication
10x = 16 * 25
10x = 400
<u>x = 40</u>
<u />
<h3><u>the number is 40</u></h3>
