Answer:
there were 11 crackers to begin with.
Step-by-step explanation:
Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.
Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3
Answer:
Step-by-step explanation:
Solve by substitution. Solve the second equation for x:
Insert the value of x into the first equation:
Solve for y. Simplify multiplication using the distributive property:
Subtract 190 from both sides:
Isolate the variable to find its value. Divide both sides by -29:
Now take the value of y and insert back into either equation to solve for x:
Subtract 6 from both sides:
Divide both sides by 5:
Therefore, the solution to the system is .
