Round 1.5 to one decimal place
Answer:
2
Step-by-step explanation:
Since rounding to the one place relies on the decimal part, the part to focus on is the .5
becuase anything greater or equal to 5 is rounded up, the answer is 2
1.5 rounded to one decimal place will be 2.
What are Places' values?Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Given a fraction number 1.5 that needed to be rounded to one decimal place. Since it's at the equidistance from the nearest whole number then we will follow the even number rule.
Rounds towards the nearest neighbor, but if equidistant, it rounds towards the even number. Both 1.5 and 2.5 are rounded to 2
therefore, 1.5 will be 2, when rounded to the nearest tenth.

help! i need an equation for this
Answer:
y = -2/3x + 8
Step-by-step explanation:
Format: y = mx + b
m = slope (rise over run) - 2/3 The graph is negative so the slope is also negative.
b = y - intercept (8)
What is the value of v? Help, please
Answer:
v = 87
Step-by-step explanation:
the angle v+39 lies on a straight line. so substract v+39 from 180 to get the interior angle for that side.
afterwards, knowing that the sum of interior angles of a triangle = 180, form an equation with all the angles and solve for v

0.4 repeating as a fraction for a mixed number
Answer:
Step-by-step explanation:
1.Rewrite the decimal number as a fraction with 1 in the denominator
2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10
3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
so the answer is
0.4= 2/5

Answer:
option a. 90°
angle 1=90°
Find the measure of ∠ J. (Hint: You must find the value of x first)
Answer:
35°
Step-by-step explanation:
set it equal to 180 because the total sum of the interior angles of a triangle is equal to 180
x+x-15+95=180
2x+80=180
2x=100
x=50
now plug it in
50 - 15 = 35

For what value(s) of w does the equation 7 + 3x - 1 = w(x + 2) have infinitely many solutions?
Answer:
w=3
Step-by-step explanation:
7 + 3x - 1 = w(x + 2)
Solve for w
Distribute
7 + 3x - 1 = wx + 2w
Combine like terms
3x+6 = wx+2w
For this to have infinite terms
3x = wx and 6 = 2w
3x = wx
Divide by x
3 =w
and 6 = 2w
Divide by 2
6/2 = 2w/2
3 =w
When w = 3, there will be infinitely many solutions

Step-by-step explanation:
The high school softball team needs to buy T-shirts for their games. The T-shirts cost $8 a piece and they only have $100 to spend.
8 a peice
This means that the money costs 8$ for each of the players. We don't know how many players there are, so we will just label the amount of players as "y"
And we will multiply 8 times y to get our answer
And then we will subtract THAT answer minus 100 to get our full answer.
