Phone calls to New York are charged at the rate of £2.90 for a 5-minute call. John’s call costs £7.86. How long (in minutes) was his call?
Answer:
Step-by-step explanation:
5 min = 2.90
xmin = 7.86
with cross multiplication;
xmin = 7.86*5min/2.90
x = 13.55=14.0
therefore x = 14min
so he will make of 14min long

-20cm
zlom
20cm
Record your answer, be sure to use the correct place value.
9514 1404 393
Answer:
1040 cm²
Step-by-step explanation:
The lateral surface area of the pyramid is the area of the four triangular faces. Each one has an area of ...
A = 1/2bh
A = 1/2(20 cm)(26 cm) = 260 cm²
Then the area of the four faces is ...
4 × 260 cm² = 1040 cm² . . . . lateral surface area

Answer:
45
Step-by-step explanation:
If you write it out it will look like this, 2x+45+x=180
3x+45=180
3x+45=180
-45 -45
3x=135
/3 /3
x=45
Answer:
x=45
Step-by-step explanation:
Straight angles/lines are equal to 180 degrees. If you add the equations together to get 180 and simplify you'll find the answer. So, start out with the equation 2x+45+x=180.
1. Add like terms. 3x+45=180
2. Subtract 45 from both sides. 3x=135
3. Divide by 3 on both sides to get x by itself. x=45
4. Just to make sure, plug in 45 for x. 2(45)+45+45=180. Sure enough, it works!

Step-by-step explanation:
The art club at a community college is selling burgers at lunchtime as a fundraiser. The club spends $8 for condiments and supplies. The cost of the meat and bun for each burger is $0.65. Express the total cost, C, as a function of the number of burgersmade, x.
Answer:
C(x)=0.65x+8
Step-by-step explanation:
According to the information given, you can say that the total cost would be equal to the result of multiplying the cost of the meat and bun per burger for the number of burgers made plus the amount spent on condiments and supplies, which can be expressed as:
C(x)=0.65x+8, where:
C(x) is the total cost
x is the number of burgers made

Answer:
a = 3b = 4c = 2d = 1Step-by-step explanation:
There are zeros at x=-1 and x=4, so numerator factors of (x +1) and (x -4).
There are vertical asymptotes at x=1 and x = -2, so denominator factors of (x-1) and (x+2).
There is a hole at x=-3, so another numerator factor of (x+3) to cancel the one in the denominator.
Comparing the above to the given expression for f(x) we see that ...
a = 3b = 4c = 2d = 1
