Answer:
The number of minutes is 10minutes
Step-by-step explanation:
Step one:
Given that the first minute of a call cost $2.30 and
each additional minute is $0.20.
let the number of minutes be x
and the total cost be y
the total cost for the situation is modeled as
y=mx+c-----equation of a line
Step two:
given that y=4.3, we can solve for the totals cost as
by substituting we have
4.3=0.2x+2.3
4.3-2.3=0.2x
2=0.2x
x=2/0.2
x=10
The number of minutes is 10minutes

Answer:
slope is -3 and y intercept is 9
Step-by-step explanation:
use y = mr + b where m is the slope and m is the y intercept
Phillipe says he cannot simplify the expression 5^c • 2^c. Complete the statement about Phillipe's claim.
Answer:
Step-by-step explanation:
[tex]a^{m} * b^{m}[/tex] = [tex](ab)^{m}[/tex]
Yes, he can!!
[tex]5^{c} * 2^{c} = (2 * 5 )^{c}[/tex] = [tex]10^{c}[/tex]
For example,
2³ × 3³ = 8 × 27 = 216
6³ = 216
The expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that, Phillips says he cannot simplify the expression [tex]5^c.2^c[/tex]
She can not simplify the expression because the bases of the expression are not same, and this expression is same as
[tex]5^c.2^c\\\\= (5.2)^2\\\\=10^c[/tex]
Hence, the expression can not be simplified as it do not have same base, and can be written as [tex]10^c[/tex]

Step-by-step explanation:
The angles of a triangle add to 180, add the angles and solve for x
Answer:
x = 14
Step-by-step explanation:
3x + 9 + 5x - 1 + 4x + 4 = 180 because triangles have 180 degrees
12x + 12 = 180
180 - 12 = 168
12x = 168
168/12 = 14
x = 14
Jason has a lemonade stand but he already made $26 he charges his customers one dollar per lemonade Kaylee has a lemonade stand where she made $16 and she charges the customers two dollars per lemonade which equation shows the number of lemonade, eggs, Kaylee needs to sell to make a higher profit than Jason. A. 26-x<16-2x. B. X+26<2x+16 C. 26+2x>16+x D. 16x+2>26x+1
Answer: B. X+26<2x+16
Step-by-step explanation:
Let x be the number of lemonade Kaylee needs to sell to make a higher profit than Jason.
Given: Jason has made $26. he charge $1 per lemonade.
Total earnings after x lemonades = $26+($1) x
= $(26+x)
Kaylee has made $16. he charge $2 per lemonade.
Total earnings after x lemonades = $16+($2) x
= $(16+2x)
Required inequality : (16+2x)> (26+x)

Katherine uses $\frac{7}{10}$ of a gallon of red paint to paint $\frac{3}{5}$ of her wall. How many gallons of red paint will she use to paint her whole wall? There is no 5/5
Answer:
1.167 gallons
Step-by-step explanation:
Given that:
Fraction of red paint used = 7/10 of a gallon
Fraction of wall painted = 3/5
Gallon of paint required to paint the entire wall:
Fraction of entire wall = 1/1
7/10 paint = 3/5 wall
x paint = 1 wall
Cross multiply
(3/5)x = 7/10
Divide both sides by 3/5
3/5x ÷ 3/5 = 7/10 ÷ 3/5
(3/5)x * 5/3 = 7/10 * 5/3
x = 35 / 30
x = 7/6 = 1.167 gallons of red paint

Answer: I'd go with C. Winter, because sleet is made from snow, which forms when it is cold
Step-by-step explanation:
Hailstones form when the updrafts generated by thunderstorms (which are more common in spring and summer than winter) quickly lift water droplets high in the troposphere, where they freeze at very low temperatures, then fall. Sleet occurs when falling snow melts and then refreezes before it hits the ground.
