John has 15 1/4 gallons of gas in his truck. John can drive his truck 7 1/2 miles on each gallon of gas. About how many miles can John drive his truck
Answer:
114 3/8 gallons
Step-by-step explanation:
To solve the question, we multiply by the number of gallons and the amount travelled per gallon:
Let's convert all fractions to improper fractions:
15 1/4 = (15*4 + 1)/4 = 61/4
7 1/2 = (7*2 + 1)/2 = 15/2
Multiply the numerators and the denominators:
61/4 * 15/2 = 61*15/4* 2 = 915/8 = 114 3/8

Write the equation of the line in fully simplified slope intercept form
Answer:
y = -0.5x - 7 or y = -1/2x - 7 (both are same)
Step-by-step explanation:
m = slope
slope = y2 - y1 / x2 - x1
-9 - (-8) / 4 - 2 = -1/2 = -0.5
m = -0.5
b = y-intercept
b = -7
y = mx + b
y = -0.5x + (-7)
y = -0.5x - 7
(negative slope)
Natasha has a job putting letters in envelopes to be mailed. in 1 hour she put 42 letters in envelopes. which equation best represents y, the total number of letters natasha puts in envelops in x hours if she continues
Answer:
36 pages .394kb
Step-by-step explanation:
that's it well done
You can use multiplication along with converting statements to symbols.
The equation for the given condition is given by [tex]y = 42x[/tex]
where y represents the total number of letters Natasha puts in envelops in x hours.
How to form symbolic expressions from the description?You need to know how to convert the statement to symbolic expression.
Suppose if it is said that a thing is increased by 4,then we write it as
that thing + 4
Suppose if it is written that 'x' objects are sold on p price per object. Since 1 object is sold at p price, then x objects will be sold at:
[tex]p + p + ... + p \: \: \: (x \: \: times) = p \times x[/tex]
Such conversion can help us to form symbolic expressions from the given description.
Since for the given case, in 1 hour, Natasha put 42 letters in envelopes, then in x hour she will put:
[tex]42 + 42 + ... + 42 \: \: (x \: times) = 42 \times x[/tex]
Since in x hours, she puts y envelopes but envelopes put in x hours came out as 42 times x, thus, both the values are equal, or
[tex]y = 42 \times x = 42x \text{\:\:(written in short)}[/tex]
The equation for the given condition is given by [tex]y = 42x[/tex]
where y represents the total number of letters Natasha puts in envelops in x hours.

How many points of intersection are on the graph of the following system?
lbrace y = x2 + 3x − 7
y − x = 9
The linear-quadratic system has
(select)
points of intersection.
Answer:
2 points of interception of (3.12 , 12./12) and (-5.12 , 3.87)
Step-by-step explanation:
y − x = 9
y = x + 9
x+9 = x²+3x-7
x²+2x-16=0
x = (-2±√2²-4(1)(-16)) / 2 = (-2 ± √68) / 2 = -1 ± √17
x = 3.12 or x = -5.12
y = 12.12 or y = -3.87
