Answer:
Tomatoes = 11.5
Onions = 2
Step-by-step explanation:
Andre wants to purchase some onions and tomatoes to make tomato soup. The recipe states that four times the number of tomatoes, , plus five times the number of onions, x, should produce 56 bowls of tomato soup. A different recipe states that two times the number of tomatoes used minus the number of onions used should produce 21 bowls of tomato soup. What is the resulting recipe for the number or tomatoes and onions used in the soup when Andre adds the two recipes together?
Let
Tomatoes = x
Onions = y
Recipe 1:
4x + 5y = 56
Recipe 2:
2x - y = 21
4x + 5y = 56 (1)
2x - y = 21 (2)
Multiply (2) by 5
4x + 5y = 56 (1)
10x - 5y = 105 (3)
Add
10x + 4x = 105 + 56
14x = 161
x = 161 / 14
= 11.5
Substitute x =11.5 into
2x - y = 21
2(11.5) - y = 21
23 - y = 21
-y = 21 - 23
-y = -2
y = 2
Tomatoes = 11.5
Onions = 2
Answer:
20&22
Step-by-step explanation:
let the numbers be X and X+2.
By question, X×(X+2)=440
or, X^2+2X=440
or, X^2+2X-440=0
or, X^2+(22-20)X-440=0
or, X^2+22X-20X-440=0
or, X(X+22)-20(X+22)=0
or, (X+22)(X-20)=0
Either,X-20=0 Or, X+22=0
•°•X=20(true) •°• X=-22(false)
•°•X=20
•°•X+2=20+2=22
•°• The two consecutive even numbers are 20 and 22.
Answer:
A = 41.41
Step-by-step explanation:
Since this is a right angle, we can use trig functions
cos A = adjacent/ hypotenuse
Cos A = 6/8
Taking the inverse cos of each side
cos ^ -1 ( cos A) = cos ^-1 ( 6/8)
A =41.40962211
Rounding to the nearest hundredth
A = 41.41
