Answer:

125 \:  \: degrees

Step-by-step explanation:

As the 2 lines are parallel

<A = <B ( Alternative Angles)

6x + 5 = 4x + 45 \\ 6x - 4x = 45 - 5 \\ 2x = 40 \\ x = 20

<A=6x+5

=6×20+5

=120+5

=125

<B=4x+45

=4×20+45

=80+45

=125

it is alternate angle they are equal each other

<A = < B

6x + 5 = 4x + 45 \\ 6x - 4x = 45 - 5 \\ 2x = 40 \\ x =  \frac{40}{2}  \\ x = 20 \\  \\

A supermarket sells milk in two sizes: 4-pint
Lesechka [4]

Please help; I’m hopeless.
Yuliya22 [10]
Well, you have to find 2 of the same number that add together to make that middle number before the c. Then you have to multiply those 2 identical numbers together to find the value of c!——————————————————————So! For number 10, 7+7 is 14, so 7 and 7 are your two identical numbers.——————————————————————Then you have to multiply them to get c! 7•7=49, so 49 is c.——————————————————————I’ll do 11 for you as well, 12+12=24, and 12•12=144, so 144 is c.

Sophie and Eleanor are making bouquets using daisies and tulips. Each bouquet will have the same total number of flowers,Eleanor
Varvara68 [4.7K]
Sophie will have a greater daises to total flowers ratio than Eleanor. To make this easier to see, let's assume the boquets have 10 flowers each, and Eleanor uses 2 daisies and 8 tulips, while Sophie uses 5 daisies and 5 tulips. Then Eleanors ratio is 2:10=1:5, while Sophie's ratio is 5:10=1:2.
