Which value of × makes 7+5(x-3)=27+5(x−3)=22, a true statement?
Choose 1 answer:
a=4
b=5
c=6
d=7
Answers
Answer:
Option c = 6Step-by-step explanation:
Given,
7+5(x-3)=27+5(x−3)=22
(Taking one of the equation)
=> 7 + 5(x - 3) = 22
=> 7 + 5x - 15 = 22
=> 5x = 22 + 15 - 7
=> 5x = 30
[tex] = > x = \frac{30}{5} [/tex]
=> x = 6 (Option c)
Answer:
Solve the equation for x:
7 + 5(x - 3) = 225(x - 3) = 15x - 3 = 3x = 3 + 3x = 6Correct choice is c
A bag of sweets contains mints and toffees only.There are 21 mints in the bag.One quarter of the sweets are toffees.Calculate the total number of sweets in the bag.
Answers
Answer:
Total number of sweets in the bag is 28
Step-by-step explanation:
let the total number of sweets in the bag be x :
[tex]{ \tt{for \: toffees : }} \\ \frac{1}{4} \: of \: x[/tex]
therefore fraction of mints = 1 - fraction of toffees :
[tex] = \frac{4}{4} - \frac{1}{4} \\ \\ = \frac{3}{4} [/tex]
therefore:
[tex] = > \frac{3}{4} \: of \: x = 21 \: mints \\ \\ \frac{3}{4} \times x = 21 \\ 3x = 21 \times 4 \\ x = \frac{21 \times 4}{3} \\ x = 28[/tex]
total sweets number is 28

A and B are supplementary angles. If A=(3x-17) and B = (2x-23), then find the measure of B
Answers
Answer:
B = 65°
Step-by-step explanation:
Two "supplementary" angles add up to 180 degrees.
Therefore:
A + B = 180
(3x - 17) + (2x - 23) = 180
"Combine like terms" on the left side: the Xs and the numbers.
3x + 2x - 17 - 23 = 180
5x - 40 = 180
Add 40 to both sides:
5x = 220
And divide 5 on both sides:
x = 44
But we're looking for B, which is
(2x - 23) = 2(44) - 23 = 88 - 23 = 65
B = 65°

Please someone help I’m stuck with this question please help show work too
Answers
Answer:
I think it is C but it could also be A
Step-by-step explanation:
So here is my explanation. The perfect answer would be {all real numbers p<=345} however because that isn't stated let me explain the answers. A states that there could be 0-345 students however it also states that there could be a fraction of a student (its some wierd thing my Algebra teacher taught me). B states that f(p) is between that but that doesn't make sense. C states all positive intergers less than 345 which means a positive whole number. That means that it is all whole students less than 345 which makes sense however I am iffy cause I think it means there cannot be 345. D states all greater than 0 which exceeds the 345 limit.

Answer:
x=19y=38Step-by-step explanation:
Let x be the smaller number
Let y be the larger number
The larger of 2 numbers is twice the smaller number :
[tex]y = 2x[/tex]
if 12 is subtracted from the larger number the result is 7 more than the smaller number :
[tex]y-12 = 7+x[/tex]
To solve for x ;
Substitute 2x for y in the second equation
[tex]2x-12=7+x\\2x-x=7+12\\x = 19[/tex]
To solve for y
[tex]If\: y=2x ,\\y = 2\times 19\\\\y= 38[/tex]

Find the equation for the line with the given properties. Express the equation in slope-intercept form.
Slope = 7; containing the point (7,-1). What is the equation of the line?
y =
Answers
y - (-1) = 7(x-7)
y+1 =7x -49
y = 7x -49-1
y = 7x -50
Answer:
y = 7x - 50
Step-by-step explanation:
the standard form for a line equation is
y = ax + b
a is the slope.
b is the intercept with the y-axis (x=0).
we know, a = 7
so,
y = 7x + b
to get b we use the point (x = 7, y = -1)
-1 = 7×7 + b = 49 + b
b = -50
=>
y = 7x - 50
