Answer:
$408.25
Step-by-step explanation:
9.50 times 40=380
9.50 times 1.5= 14.25
14.25 times 2=28.50
380+28.50=
$408.25
Your speed is 3.9 miles per hour
Answer:
It is the number written out to show each digit
Step-by-step explanation:
Let's say you have the number 459
you write out the hundredths place, which is 4 times 100
you write out the tenths place which is 5 times 10
and you write out the oneths place which is 9 times 1
the full thing written out is 459 = 100×4 + 5×10 + 9 × 1
Answer:
(3, 50) and (14,303)
Step-by-step explanation:
Given the system of equations;
y=23x–19 ....1
x²–y= – 6x–23 ...2
Substitute 1 into 2;
x²–(23x-19)= – 6x–23
x²–23x+19= – 6x–23 .
x²-23x + 6x + 19 + 23 = 0
x² - 17x + 42 = 0
Factorize;
x² - 14x - 3x + 42 = 0
x(x-14)-3(x-14) = 0
(x-3)(x-14) = 0
x = 3 and 14
If x = 3
y = 23(3) - 19
y = 69-19
y = 50
If x = 14
y = 23(14) - 19
y = 322-19
y = 303
Hence the coordinate solutions are (3, 50) and (14,303)
